It's not a sexy thing for me, it's comfortable. I don't need the support so no bra feels best.

Sorry if I am misinterpreting, but I wasn't suggesting not wearing a bra is a choice I make to be "sexy", either for myself or others.

The only reason I ever wear a bra is if I am concerned that people will perceive and sexualize the shape of nipples under clothing. Even then, I have tank tops with padded front sections and a bit of elastic for "support" (not needed). Despite being way, way better than a traditional bra, they are still a sensory nightmare by the end of the day.

I'm clarifying this more for the post as a whole. There are quite a few comments on the post that seem to think that when people say they should be allowed to wear what they want the main conflict is people being restricted from expressing themselves in a sexual manner. Sure, that is one reason people want to have freedom of choice with clothing. Like you mentioned, some people don't want to be pressured into gender norms ("unnatural barbie doll look"). I guess my not wanting to wear a bra is also about gender norms. Nipples showing prominently on a male presenting person might be seen as uncomfortable sometimes but not nearly to the extent it is on female presenting people.
