Yeah, I didn't want to be nasty about it, but the article saying that 37" is the median adult American woman's waist measurement is... pretty shocking. Like, I'm a 6' slightly out of shape dude and my waist fluctuates from 33-35". You'd have to be pretty large to have a feminine figure and have the narrow part be 2" wider than my widest section.

Have you measured your waist? Vanity sizing is a thing in men’s clothes too.

No you're not. That's the size your brands of choice advertise to you so you think that you're slimmer than you are.
