My concern was mostly hygiene to be honest and I think we have to be more considerate of people that don't necessarily go to the gym to see someone going around with her boobs out when she could wear a more covering sports bra or a tshirt. Just because we can it doesn't mean we have to, having a slightly longer pair of shorts won't influence performance and is actually cleaner and respectful. I don't see men working out without a tshirt. I am not saying women can't wear a sports bra, I was wondering if it's really necessary to make it so small. Do women really want to wear that or society profits from women being objectified and promoting this kind of clothes? Because I don't see a practical benefit in this at all, it's a trend.
