“Vanity sizing” is a term for the industry’s practice of inflating the dimensions associated with a particular size tag over time. What was considered an American size 8 a decade ago will pass for a size 4 today. Size inflation becomes more extreme the further back in time we go.
I’m a pattern maker. The pattern maker is the person most intimate with sizing in the clothing factory; we work in production. Now, because we’re not big names or famous, people don’t bother consulting with us so you never hear our side of it. Not only have I never “vanity sized” anything in my 27 year career, I don’t know another pattern maker who has either. Bear with me here.
I’m glad you’re interested in this topic and intelligent because this is very complicated to explain which is why we can’t explain it readily or easily to the average consumer which is why this vanity sizing myth is so rampant. I’m glad you’re bright because you’ll understand what “normalizing to the population” means because that’s what we’re doing. Now, if sizing didn’t normalize to the population, we’d still be making clothes designed for people in the 1800’s. If manufacturers didn’t adjust the sizing of their products (to include buildings, furniture etc) you wouldn’t be able to get in the door without ducking. So, with everybody from architects to industrial engineers “vanity sizing” (”normalizing”) products in your environment, how come you’re not complaining to them that the size of their products haven’t remained static? Rather, it’s the opposite usually; one specific example is the size of airplane seats, those aren’t big enough but guess what, they won’t be “normalizing” seat sizes because they have to redesign the entire PLANE!
Sizing evolves, just like people do. Sizing is not a fixed mathematical construct, but a social one (it used to be mathematical but meaning was wrested from pattern engineers before my time) -so there’s even a social history component (I also wrote three entries about that). And an economical one, and a buyer one. Sizing is even dependent upon how a manufacturer organizes and employs their product development system in accordance with the dictates of their retail partners. But most of all, sizing is related to efficient material utilization, which doesn’t mean cutting smaller to save fabric when we’re obviously discussing the opposite. I’ll explain.
Consider: most manufacturers cut a size range of 6-14, nearly all do, if not, 8-16. Now, sales wise, the vast majority of orders are in the center of the size spread. Now, as the average person gets heavier, over time, sales begin to weigh in (excuse the pun) on the upper end of the size range so the size spread is off kilter. Now why does this matter? It matters because of marker design and allocation (arcane as I said). To make an efficient marker (keep fabric waste to a minimum) you need balance. For every size 6, you need a size 14. For every size 8, you need a size 12. The 6/14 and 8/12 balance each other in a marker. So, if you have orders for too many of the larger sizes and not enough of the smaller sizes because people are getting fatter, you don’t have balance because now you need 3 size 12’s for every size 8 or 2 size 14s for every size 6. So, you change the sizing structure. This way it rebalances. Otherwise, if they didn’t do this and the given measures that constitute a given size remained static, the smaller sizes would drop out of the size range altogether. A manufacturer would be cutting lots of 12’s and 14’s -with pressures on the upper end of the size range, in sizes they don’t even offer! If they added those sizes (dropping the smaller sizes, the sales of which are too few to cut in production), they’d end up in plus sizes which means a whole new market, whole new stores, whole new sales reps and even assuming that not “normalizing” to the population would work (in theory) it is just too costly to contemplate if you have established distribution.
Also consider retail. If a manufacturer didn’t normalize to the population, their sizes would -over time- “run small”. Retailers won’t like that, buyers would have to know the line intimately and they just don’t. They’d be putting static size 10’s on a rack that were in effect, two sizes smaller than the competitor’s size 10s. That confuses customers too. For better or worse, they want size 10’s across manufacturers to bear some resemblance of consistency. Two sizes smaller isn’t.
How this phenomenon started is anyone’s guess. It is thought that vanity sizing is “designed to satisfy the buyer’s wish to appear thin“.
Actually, there’s no guessing except by the average consumer.
This boosts self esteem and thereby ensures the sale of a garment. Designers and manufacturers were quick to realize that there was money to be made by satisfying perceived insecurities.
What amazes me is that you think sizing is about *you* -consumers- your head games that we’re trying to make you feel better about yourselves. I don’t know who started that myth but it’s not! It has nothing to do with *you*. Since when have large manufacturers cared about the consumer? (as you can imagine, I’m not real popular with manufacturers either but assign sins where they belong). Rather, it has everything to do with internal material utilization processes within the limitations of the manufacturing industry. Iow, what we call “allocation” based on the derivation of sizes with regard to our respective markets.
If you’d like to learn more about vanity sizing, Wikipedia is a good place to find related articles. What are your thoughts on downsizing size tags as a way of fooling us into a false sense of security? The increasing dimensions of garments have subsequently caused retailers to introduce additional size designations at the low end of their size ranges (0, 00, or subzero sizes).
See, right here your POV is questionable. As prosecutor, judge and jury, you’ve pronounced us guilty without considering alternatives. It has nothing to do with how you feel about yourself. IMO, manufacturers are doing a poor job of meeting consumers needs, so why would they go to the bother of catering to your self esteem? I notice you linked to wiki’s vanity sizing entry which is pov questionable, error-rife and mis-cites their own source material. It’s a pity you didn’t read all their references, particularly the only one written by the “fashion industry” called, The Myth of Vanity Sizing. I mean, if you’re going to say we do all of this stuff, you should at least hear what we have to say for ourselves. Here’s other entries on the topic, not included are three additional articles on the history of women’s sizes.
Fit and sizing entropy
Push manufacturing, subverting the fit feedback loop.
Sizing Evolution.
Consumers are getting bent out of shape over a non-issue when they should be holding manufacturers responsible for producing poorly fitting apparel. Many of them (mostly big box store labels and importers) just don’t give a da_n. Many big brands think you only care about the label, the name, the logo, the “brand” and their spending priorities reflect that. Manufacturers are spending less than half what they used to on product development, the savings they’ve thrown into advertising, marketing, selling you on their image. Imo, clothing should be about YOU, not about the brand.
