Is it socially acceptable to not wear a bra in public? (no pervs)?

I stopped wearing a bra in January of this year and I haven't had any problems. If you're planning on going braless in a shirt where you think that people might see your nipples, then wear a tank top underneath or buy pasties or something.

I honestly don't know I would say it is down to individual choice, but not wearing a bra in public could easily make you more of a target for perverts and people on the prowl to force a one night stand, i would not recommend it.

I never wear a bra in public nor in private. No problems for me.

Do whatever you want. If you dislike the attention you get, then change the way you present yourself. Whether you have fake breasts or not is completely irrelevant to your question.

In America, people will frown and be grossed out (or hit on you).

In Europe, not so much.

Don't ever do that in Mexico. Extremely dangerous.

I think it's not a huge deal unless it's disgustingly noticeable.
