For everyone struggling with clothes sizing and having a hacker mindset, I can't recommend enough buying a sewing machine (~100EUR on a used market, ~150 new gets you a reasonable starter one you won't outgrow any time soon) and giving clothes alterations a try.

Finding a tailor that understands you / you agree with is an option too, if time is a hard limit (though I'm not sure it's altogrther that much quicker).

In my case, I started with tailors, but kept running into small misunderstandings. Also, my taste keeps evolving.

Start small with simple stuff, ideally old / second hand cheap clothes. Shirts, T-Shirts and bodice waistlines / "darts" are almost trivial once you can follow a straight line. First one will take a while, second will be much quicker, by third / fourth it's almost a routine and you can start iterating on your own preferences. They likely "will" evolve as you keep wearing the altered clothes.

Depending on how much help you can get in the beginning, with maybe a 2-3h intro on how to use a sewing machine done by a friend who has sewing as a hobby, I'm pretty sure most people should be able to get their first alterations done within 4-5h. By second or third attempt, this time should be down to around 1h per item, including some setup (pinning - trying - ironing). At that point the DIY option is probably quicker than going to a tailor.

This is a great use of data to make a compelling case that sizing sucks for women's clothing!

I do wish it attempted to answer the question at the end, though: "Sizes are all made up anyway — why can’t we make them better?"

Like, why doesn't the market solve for this? If the median woman can't buy clothing that fits in many brands, surely that's a huge marketing opportunity for any of the thousands of other clothing brands?

This is, to be clear, a sincere question - not a veiled argument against OP or anything! It seems like there are probably some structural or psychological or market forces stopping that from happening and I'd love to understand them. Same with the "womens clothes have no pockets" thing!

If you shop online and use raw measurements, then it will both fit and be available.

The real concern I have is how the large majority of westerners are overweight or obese. That's a serious issue way beyond the practicality of buying clothes

Semi-related thing that suprises me as a man (this is in Europe):

I go to a clothing shop at the start of a new collection, and look at men's shirts for a given type:

- there's 10 XS, 10 M, 10 XXL versions

I go towards end of the season:

- there's like 1 M remaining, but 8 XS, 8 XXL.

Like if they were surprised and had no data that most population is M.

At a previous employer this was a problem we identified (and larger retailer customers) had recognised, although for other reasons. We had developed a size recommendation system for them, that used real product measurements in every size and a method of obtaining your body measurements from fully clothed photos. We also offered a statistical average measurement set for those who couldn’t/wouldn’t take photos of themselves (privacy was important to us, and there was no need to undress).

We were able to give details about fit comfort across many measurements for each size, but this feature was basically unused. 99% of users used the statistical average body of themselves instead of themselves, which actually exacerbates the body type problem.

Another interesting thing about the industry and the grading process we learned; many retailers had no measurements for their own clothes except the reference size. This was much more common of higher end brands.

1 last thing; some global brands actually have the same size name on the same product represent a different size in different region (eg an SKU in size S in US may have different measurements to the same SKU in S in Asia)

If the author reads this, I think it would be great to use international units as an option, and perhaps by default.

I have no idea about imperial units so it’s a difficult read.

belZaah - 2 hours ago

What ticks me off in this is the statement, that a certain body shape is “unattainable for most”. I’m pretty sure the author does not have the data to back this up. Difficult? Yes. Requiring commitment? Absolutely. Unattainable? No. I really don’t care what body shape anyone is comfortable with. But as someone, who has struggled hard all his life not to be obese, I find it irresponsible to outright declare something that’s absolutely doable by anyone as “unattainable”. Being able to attain it might be someone’s only hope and it’s just wrong to take it away.

There's a European standard designed to fix this, which just uses body measurements, although I've never seen it used. https://en.wikipedia.org/wiki/Joint_European_standard_for_si...

Women's sizing is so dumb. They could just provide inches or cm like they do for the men, but for some reason (well for marketing reasons, as discussed extensively in the article), they use these random sizes and numbers that aren't consistent and change over time.

I think this is why stretchy materials are getting more and more popular. The women in my house use stretchy pants almost exclusively, because they are much more forgiving with body shape. As long as the waist fits, the rest will fit well enough.

Rendello - 15 hours ago

Interesting visualizations, but I don't understand what the thesis is. To me, the conclusion says:

1. Luxury fashion thrives on exclusivity, which is exclusionary.

2. Clothing size standards do not match diverse body types.

3. There is no sizing standard, and companies size however they want.

d--b - 7 minutes ago

Here's an asumption:

When you get into the overweight category, sizing becomes a lot more difficult, because then the ratios that are relatively standard for non overweight bodies (like waistline to tallness) completely break down.

So now you don't need just one parameter, but at least two: waist and tallness. And this causes the number of different sizes to explode. So instead of (S, M, L, XL, XXL, XXXL, XXXXL), you'll need (S, M, L, XL, XXL, XXXL) waist x (S, M, L, XL, XXL, XXXL) length. And it becomes unmanageable for brands to cover all the different sizes without having a large amount of waste.

Men trousers and shirts do this, because generally men fashion don't change that fast, so the brands can carry many models for a longer time period.

It’s worse for women, than men, but all tweens/teens have this issue, and it drives parents nuts. Also, these kids are chronically insecure, and the need to be "fashionable" is intense. I remember hating JNCO pants, for my daughter. To be fair, at least they were baggy.

I have similar issues with shoes, and I’m in my 60s. My wife refuses to buy me shoes.

If I buy Clarks, I’m size 9. If I buy New Balance, I’m size 10.5. If I buy Hoka, I’m size 11. It’s crazy.

magneticnorth - 15 hours ago

"The average woman’s waistline today is nearly 4 inches wider than it was in the mid-1990s."

I assume they mean circumference rather than diameter, but this is still a shocking increase in only 30 years. I knew the obesity epidemic was an ever-increasing problem, but this really puts it into perspective. I wonder if we'll ever fully understand the causes behind this rapid shift.

brailsafe - 3 hours ago

Reminds me of how annoyed I am that Eddie Bower is closing, because there's very few other retailers that sell affordable medium-tall mens sizes with extra long arms. People who don't have anatomical size issues don't seem to understand how annoying it is to find clothing that doesn't fit some statistical average. I have to get lucky to find a medium that fits a bit thinner, but then usually I'm stuck if that company decides to change their product. If I need formal wear I need to find a niche company and pay niche prices. Feet larger than size 12? Sorry. Tall but not a rugby player? Sorry.

The of the only reasons I've been wearing the same pants is because I haven't found anything else that fits well

thesumofall - 3 hours ago

Beyond all, I think cost is a major driver. A key difference in cheaply made clothing vs more expensively made clothing is the sophistication of the tailoring. However, the interesting side effect is that cheaply made clothing sort of fits everyone badly while more expensively made clothing either fits you really well or not at all. If(!) you care about well-tailored clothing you're either lucky that one of the brands fits your body or you need to go the custom-tailoring route. Custom tailoring wasn't anything special for a long time but we sacrificed it to our desire for cheaper clothing (which isn't necessarily a bad thing!)

I might have missed this in the scroll format but is there any reason not to drop the qualitative size names and just use an actual dimension or two?

_trampeltier - 3 hours ago

People change, not just since the 90s. Just look an old movie, like Dirty Harry, or look pictures from athletes in the 70s, 80s. It does not so much plays a role, as long you try in a store. But online it sucks very much right now. Recently I ordered a pair of pants, and it was something like 3 sizes smaller, than the same model in another color. I'm not sure, if online stores and factorys think people would not return the item and just order a size larger or smaller again. I think thats also a point where the EU should push, a true size with cm.

miav - 15 hours ago

It is genuinely incredible how well-fitting clothing is only generally available to some one-third of women who fit well into the anticipated height-waist ratio. Petite options exist in some places, but god forbid you're tall - your choices will be limited to "too short" and "too short and also too wide" if you try to go for a size up.

choilive - 14 hours ago

If we can have mass produced fast fashion from runway to store in weeks...

Why not tailored clothing at scale? Have a set of portable body measurements that can be sent to any retailer - make an order and have it sent from factory to door in a week or two.

Or get a size that is close enough - bring it to your neighborhood tailor. Most alterations are simple and not very expensive.

Unfortunately sizing is just a leaky abstraction. You are trying to distill many variables into a single dimension. It will never be particularly great.

I as a small male struggled a lot when I started exploring fashion. Nothing seemed fitting to my body. You know what happened? I just gave up at some point. I rarely buy new clothes now. I absolutely don’t buy anything before I try them on.

I buy shirts with a collar and length size. Surely it can’t be that hard to do the same with waist size?

Wait, I buy my pants with a waist and length size. So the problem is already solved?

arh5451 - 4 hours ago

Im interested to understand what is the reasoning for using the median and not average. I'm assuming the population is likely a perfect bell curve (more or less) in which case median would represent a higher waist size than using the average. This would seem to invalidate much of the presented thesis. I appreciate the detailed analysis of body shape, I think it is quite interesting.

the real insight here isn't that sizing is broken. Everyone knows that. It's that fixing it would require brands to admit their current customers don't match the label they've been selling them. "You're not a size 6, but size 10" is bad for business

Makes me want to learn to sew to make my own clothes. I've wanted to for a while because seams on clothes always bothered me. (Not for taste or fashion, but just because I feel like the technology to make a seamless clothing product must exist.)

> Cultural narratives around vanity sizing often square the blame on female shoppers, not brands. Newsweek once called it “self-delusion on a mass scale” because women were more likely to buy items that were labeled as sizes smaller than reality. But there’s more to the story.

> Vanity sizing provides a powerful marketing strategy for brands. Companies found that whenever women needed a size larger than expected, they were less likely to follow through on their purchases. Some could even develop negative associations with the brand and never shop there again. But when manufacturers manipulated sizing labels, leading to a more positive customer experience, brands could maintain a slight competitive edge.

How one can seriously write the same thing twice in form of contradiction and make different conclusion?

nn3 - 8 hours ago

What's also annoying is that sizes of the same clothes change. I have a pair of jeans that I ordered on Amazon in 2020. It happens to fit me great. So recently I decided to order two more of the same. I got exactly the same model with the same size on Amazon, just with different colors. But neither fit very well, they were far wider. The first one had such a horrible fit that I immediately sent it back. The other I can wear, but it's quite different from the other perfectly fitting one. Why are they doing that? It's insane.

So these sizes (kid, teen, adult) are kind of ridiculous on their own, and combined with the different international systems even more. If you look at the tongue of a pair of a pair of sneakers for example, sometimes there will be four different numbers for international markets.

I wish they simply measured clothing in centimeters, and all the complexity could be left behind.

throwawy_gender - 2 hours ago

I need to say this out loud: Can you really imagine a similar article being written about men's clothing sizes? Seriously, get in shape. Lose weight. I don't care if it takes drugs (ozempic, whatever). If women in other highly developed countries can have a median body weight much less than American women, then I am not very symapthetic to their "clothing size crisis".

uberman - 15 hours ago

Great visualizations but you can't buy a shoe without knowing that a 10 in one brand is not a 10 in a second brand or that for example you need to size down when ordering Dr. Martens then there is no way to expect clothing to be more accurate than a shoe.

observationist - 15 hours ago

Why bother with a rational, descriptive, functional system when you can use vaguely aggressive and hostile terms that subtly impugn the buyer and allow incredibly deceptive and manipulative marketing?

And hey, they don't really need pockets, anyway, right?

edit: Really should have used the /s, I guess - women's clothing has some appalling aspects to it, one of which is notoriously tiny pockets, which is a source of frustration for many women. For some, it even comes as a shock when they find out men can do things like put phones in their pockets.

The emotional manipulation surrounding many women's products is a different beast entirely from what men experience, generally.

I've always been struck by how outrageously exploitative and anti-consumer the textile industry is in so many ways, and how people just normalize it and don't even discuss it.

Not just in sizing, which is also a problem — my polo shirt and dress shirt sizes vary between M and XXL depending on the brand, and even my shoe size can vary up to 3 numbers, it shouldn't be rocket science to establish some quantitative standards.

There's also the issue of buying a polo shirt and having it bleed because they've decided to save a few cents on the color-blocking product, and in the first wash, it ruins not only the shirt itself but the entire laundry load.

And the fact that a cotton garment may or may not shrink, and it's a complete lottery how much it will shrink, so sometimes even trying it on in person is useless.

And then there's the fact that someone up there decides that this year a certain trend is "coming" (let's say, pants with buttons instead of zippers) and that's all they sell. If you like zippers and you need to buy pants that year, tough luck.

And all of this is compounded by the fact that even buying expensive doesn't guarantee you'll get spared from all this nonsense... I'm not a cheapskate at all, I don't mind paying if I know a garment will be reliable and durable, but sometimes you buy a designer item and the quality is absolute garbage.

All of this, by the way, is much worse in Europe than in the US (I'm not entirely sure why. Maybe it's because in the US you always use a dryer, so they have no choice but to make clothes a bit more robust for that market).

If other industries did these things, consumers would be up in arms. If any other product seemed to behave well when you superficially check it on the store, but then completely failed on very first use (like a shirt that shrinks or bleeds), you would return it. But in clothing all of this is normalized.

It also amuses me when people complain about the carbon footprint of AI: if they saw the footprint of the textile industry (compared to the actual usefulness of clothes designed to last for one season and be replaced...).

Capitalism at work. As a male and full time woman’s wear person who has been married to a woman for 17 years I’ve experienced these truths from both sides. It’s funny how rectangle and inverted triangle body shapes are oft ignored as this would open up the market for clothes to be genderless.

The lede is sort of in there, but buried - or at least not talked about from an economic perspective:

Right now, women consumers put up with one-ish body type (although fit model shapes vary by brand) - manufacturers thus make up to ten sizes or so of any given garment. Google fashion industry waste if you want to learn some depressing things, but - because of fashion lead times, production methods, etc, a lot of these clothes will not get sold. So there’s production waste.

There are roughly 10 core body types according to this website. So, to make ‘properly’ shaped garments for a much larger group of women is going to take roughly 120 different garments for a single design.

This just isn’t going to work for manufacturers given current production methods. I’m working on a fun sweater company right now, and it’s a very analog process - with humans and production and yarn all in different countries - ending in a single garment for analysis that is then put on a model for photography. I cannot imagine trying to scale it to 100 different shape/size combos.

Upshot - right now: choose from the following:

1) create mild differentiation and hit a product target that blends looking good on the site/shelf/model with one that looks good on the customer; keep 90% of the market

2) lean in hard on one of the “10”-ish body types - give up the rest of the market, but have happy customers

3) Try to sell stuff that can get auto-sized properly via algorithm and delivered “on-demand”

Most big companies are big, and therefore chose 1. Some smaller companies chose 2. In the happy circumstance that they chose 2 for conventionally attractive bodies, you’ve heard of them (Chanel). Some have transitioned into this space over a longer period, like Burberry. If you’re not a target customer, they may still have fans, but you might not have heard of them, e.g. Good American.

A few companies have tried 3 — direct to consumer via brick and mortar retail — (there was an MIT company deploying Shima Seki knitting on Newbury street in boston years ago), but they inevitably seem to move to a fast deployment D2C shipping model.

I think this is likely because if you go into a boutique you do not want to pay $600 for a garment and then have to wait three hours for it to get made. Online this feels more palatable.

So, we’ll probably see some continued innovation on the robot-knitting side of the world over the next ten years. In the meantime, companies mostly do what makes economic sense. And, it’s worth noting, operating the “automated” knitting machines and designing for them is no joke, it’s hard — really hard, and the software can be abysmal. So, this is an industry that’s a long way from rapid change, at least right now.

Men's clothes have gone through the same process over the course of my lifetime. For instance, I wear the same brand and size of jeans that I did in college. The waist size back then was broadly accurate to the actual size in inches, but today, thirty years on, I weigh ~20lbs more, and that waist "measurement" has up-sized along with me. I guess it's meant to flatter me, but is it really fooling anyone? I guess, based on other's comments in this thread, that it does, and vanity sizing works, which is just sad.

(Then there are men's "relaxed" fits, which bear even less relationship to actual measurements. Maybe "slim" sizing is closer to the old system? Even when they fit my waist - like, six nominal inches bigger than standard! I'm not that much wider - they don't fit my legs, so I don't know.)

None of that's anywhere close to as ridiculous as women's sizing, but give 'em time and I'm sure it will be.

harrall - 11 hours ago

Women have it much worse but it’s the same with men’s clothes.

A “large” men’s shirt from Uniqlo is totally different from a “large” from Volcom and so on. Start making your own clothes and realize there’a a thousand dimensions to a shirt and “waistline” is barely scratching the surface.

Don’t get me started on shoes, especially if you have wide feet. Something like “wide” means totally different things. Unlike clothes, poorly fitting shoes will absolutely destroy you.

At least pants have WxL.

I’ve come to chalk up clothes sizing as a natural complexity of life.

socalgal2 - 15 hours ago

This feels almost like a made up issue - like, "we want to considered victims so lets make up something to whine about"

A few concrete issues:

(1) they complain there are no international standards - And? Why should Japan, who's average size be much smaller than the USA be required to use USA standards? Their population doesn't need to care about people outside of Japan. You could say they should relabel the clothing, all that would do is raise the price and effectively make poor people poorer.

(2) they show people "Americans" get heavier - That might be reality but maybe being reminded you're wearing extra large is a good thing? Like you really are "overweight" and that's unhealthy. You can choose to ignore that but the rest of us aren't required re-label you as something you're not

(3) They graph high-fashion like LV and show they don't have large sizes. So what? Ferrari doesn't make cheap cars. I'm not required to make product that suits you. If you don't like what I'm offering, pick some other company's products. I don't like donuts, I don't go to a donut store and demand they offer pizza. Nor do I go to jeans store and demand they carry suits.

(4) they complain about vanity sizes - why is this an issue? Try the clothing on. If it fits buy it, if not don't. That's what I do because duh!, different people and companies follow different patterns. Some fit, some don't.

If you want to fix any of these - feel free to start your own clothing brand. Clearly you believe the market isn't being served. If so, put your money where your mouth is rather than requiring others to risk theirs

What a lovely website, and the torso silhouette sizing diagrams are invaluable.

I'm not the target demographic, but the main problems I have are proportions not simply waistsize. I was under the impression a size range [xs,s,m,l,xl] was supposed to adjust girth (bust, waist, hip, thigh) while leaving the vertical measurements unchanged (inseam, rise). Because nothing fits, I purchase a sizing range with the intention to keep just one and return the rest. It makes for pretty funny discussions: $500 on <clothing> WTF! Anyway I've started measuring clothing dimensions and have found that the brands I shop generally tend to adjust other dimensions in a 2:1 girth:height ratio. This means that if I want a snug waistline I'll have a tight crotch or be forced to wear pants on or below the hip. Now I like wearing pants somewhere between waist and hip. There's a band of fat/padding/sinew (?) just above the hips that makes for the sweet spot in terms of comfort and utility. I don't understand clothing that's meant to sit on the hips... so uncomfortable.

As a rule of thumb I tend to shop Asian clothing stores in the US because they tend to better fit my proportions, but lately it's become hit-or-miss, i.e uniqlo. I've also got some pretty weird proportions due to my exercise regimen.

Also you've got to love brands that don't provide actual sizes. Wtf!

Size ranges are almost always infuriating. I sample my measurements throughout the day to get an accurate range and average. This is invariably what occurs:

store sizes: x1-x2, x3-x4, x5-x6

me: x2-x3

Infuriating! Non-contiguous ranges suck!

Then there's this little unexplained morsel:

> The average woman’s waistline today is nearly 4 inches wider than it was in the mid-1990s.

Their data is drawn from the US, so I'm wondering if this is related to the obesity epidemic, or a general change in silhouette. I was under the impression that historically, humans are trending taller and skinnier.

As a short adult male (5'5" - 165cm), it's always been difficult to find pants or jeans with a 28" inseam. Surprisingly, AmazonBasics line of clothes is one of the few mass produced consumer brands that has this size. Niche alternatives like Peter Manning are expensive, so it's great Amazon does this.

diath - 14 hours ago

The issue is not the sizes, the issue is the obesity epidemic. According to CDC [1] the average woman in the US is 5'3" weighing 172lbs. That's not just overweight but rather first degree of obesity. I guess you could argue that sizes should catch up to the demands when half of your population is straight up fat but I feel like a better angle would be educating people that 1500 kcal worth of Starbucks sugar for breakfast is not healthy.
