I wonder if understanding a particular brand's sizing drives up repeat purchases.

Yes. This is specifically a driver for having brand-specific sizing: knowing what size I am in Wooland Jade does nothing whatsoever to help me assess a potentially cheaper option in Uniqlo Whatever. It's the same lock-in effect as cloud APIs, only implemented through attributes instead. Imagine the chaos in the guitar market if the "bass" in "bass guitar" had up to +/-25% variation between guitar manufacturers — it would be a total nightmare trying to cross-shop guitars away from your current one, and lots of people would just end up glued to a brand so they don't have to do the hard work of assessing 'is this within +/-5% of the bass that fits me now'.

Flipside: drastically changing a brand's sizing standards has repeatedly driven me away from long-time favourites.

This happened to me several times from the 1990s through the aughts. Literally between one shopping session and the next, the same style of clothes (tops, bottoms) which had fit perfectly no longer did, resulting both in a set of returns (of clothing) and non-returns (of myself, for future purchases) to those stores. As someone who generally dislikes the shopping experience, additional and insurmountable frictions such as these are absolutely fatal.

More recently (as I've just commented) it's the widespread adoption of stretch fabrics in non-athletic wear. I may want stretch in some of my workout clothes. I don't want it in my street clothing.

Speaking for myself as a bloke, yes, 100%. If I know stuff from a particular brand fits me well, I’m going to buy more from that brand.

  • I always find it frustrating that most stores turn over their stock so often. I find a shirt I like then go back to buy another and it's gone.

  • 100%. For a time whoever the gap shirt designers measured up for their XL size must've exactly matched my build and height, and had extra long arms the same length as mine. So it was an easy way to get a shirt that fit right, for me.

Yes but it’s multiple dimensions other than just waistline. e.g Some brands make boxier shirts and others use longer cuts.

Because “my style” prefers one over the other, I know when I buy from a certain brand so it’s going to fit on me better.

If if waistlines were standardized it wouldn’t really account for all the other measurements.

  • There's also different definitions of waistline size. Pant sizes "lie" because historically most pants sat further up your waist, now that many of them sit on your hips, they give you a measurement as if they were still sitting higher up so you can compare between the fits with the same number.

    Really the only bulletproof solution here is to just go try them on in store and see which fits best.

    • Pants sizes also lie because they don’t take into account the rise necessary to provide horizontal waistline on women with an angle at their rear waist-to-hip incline. A 14 low-rise waist that flops down at a thirty degree tilt in the front is a worse fit than a 12 mid-rise waist that doesn’t, for example.

  • It's a great point that I think the article also touches on. Bodies are of many shapes, so the sizing question is as much about, possibly more about, shape as it is mapping any particular dimension to a scale.
