It would be nice, though I just don't see it happening. Still to this day, onset at 33, now 40, I've yet to see a man in a bra of any kind. I know there are bras that are "invisible" but I feel at this stage I could see it if it was there. Being so hyper aware of bra lines and such due to my own insecurities of being in one for awhile before getting ok with it. I feel it would have been just so nice to see a guy in a bra that would make it feel not so alone. I imagine most men who grapple with needing a bra find themselves in a similar issue. Being the only one they see in one. Online, sure. Community groups like this, of course. At your local home depot, grocery store, park, gym, etc....not so much. I feel until men regularly wear one or at least enough men do, it just isn't gonna happen. And given how fragile the male ego is, I feel the bra is just not gonna be something we see become normalized for masculine men who have breasts.
