So typical sizing for women's mtbiking?

[Crankin]

Those measurements sound like they might be for an extra small male!
I am about the same size as you Shooting Star and I know my hips are about 36 inches, give or take. Sizing has become so "vanity" prone, that I can only wear xxsmall petite sized tops now; so I am limited to Banana Republic and Athleta.
Yesterday I wore a sweater that is about 8 years old. It's a petite x small and fits perfectly. Now that same size in that brand would be huge on me.
Cycling clothes, however, I consistently wear xsmall women's sizes.

Could it be that the measurements are in centimeters, and that's a REAL XS? The inseam is a clue.

I've said it before, I'm more or less the same size as I was 25 years ago when I wore size 10 or 12. Now I'm a 2 or 4. More worrying is that 15 years ago when buying an event T-shirt, I could often squeeze into a youth XL - now, a youth M is usually baggy on me. But 40" hips for an XS just doesn't sound right. I'll bet it's 40 cm.

Men will typically have narrower hips than women for the same waist size, not wider, so that can't be it. But men do not wear capris that I have ever seen. If those are men's bottoms, it's got to be metric.

But that would be <16", so metric doesn't explain it, either. 13.5 inseam sounds like seat tube length...the whole chart looks nonsensical. The waist and hip look like what I think of when I think of a L or a generous M.

It would if the XS was meant for youth... a lot of gear in the motorcycle world doesn't have separate youth sizes, and there's a lot of crossover between off-road two-wheeled sports, in gear and manufacturers as well as ridership... Boys don't change shape as they grow into men, nearly as much as girls do as we grow into women.

But 16" hips?! Only a toddler would have hips that small. And that makes the waist only about 12" around. I'm thinking that chart has some typos. A 13.5cm inseam would be in-utero.
