"Considering that women's clothing is designed (mostly) by men..."
I understand what the media likes to say. And I'm sure they have their reasons for doing so.
However, real-life "boots on the ground" (i.e., people who actually work in the industry, which includes plenty of GG's) say otherwise -- that most are, indeed, GG's.
That's been my brief professional experience, as well... More GG's than men, with a higher-than-normal prevalence of gay males, to boot.
Eh, believe whatever you want to believe, as long as it suits one's narrative?
BTW, don't confuse a male CEO, with someone who actually designs the stuff. The CEO is there to run the company, itself, that it's it. Much different responsibilities.
P.S. GG's here have already explained the smaller pockets thing.
