Aside from men being horny in the 1800s, and this being a holdover since that time, is there any actual reason why this hasn’t changed?
If society was dominated by women, would this be more likely to change?
I was sweating my ass off hiking in the hot sun, and the question has been bothering me all day after my top soaked through with sweat.
Kudos to your friend going through with a reduction to pursue her passion!
In my case, I have a very small band width, so I cannot shop in regular stores. (In my city, there is exactly one shop that has my size.) As a teen and young woman, I simply didn’t have the money to even consider a 50€ sports bra, let alone a 100€+ one. And since the selection is super limited, I didn’t even find one in my size that would - no matter the money - give enough support for comfort.
Funnily enough, regular wired bras with cups still ended up giving better support than any sports bra I could find. But they still only work so well. (And I, by far, wasn’t as passionate about sports as to get a reduction, or spend my limited bra money on a semi working, ugly sports bra.)
