Basically, I find it gauche to see someone’s underwear in public, not cute or a fashion statement. It’s like a “people of Walmart” meme that makes me want to look away, so if you are looking for some type of approval or attention by being a man with a bra beneath an open shirt, it won’t be coming from me. I would likely avert my eyes and keep moving if I saw someone flaunting a bra deliberately outside of a club or costume. Inside, my head would be shaking as I thought, “Bless his heart.” I’m not perfect. Far from it. I admit that I would be judging that fashion choice hard, but inside my head.
