Sure. So far as I can tell, the taboo boob is more of a cultural fixation than a conclusion from rational duress.
It'd be weird to get use to, but that's no big deal. I figure this would be more bad than good tbh, as I figure there are a lot of ugly, saggy boobs out there, and those people who do not care about their appearance will also likely be the ones who don't care enough to put a shirt on.
