As in- is it polite, or as in is it comfortable? Personally, I'm the kind of girl who always wears a bra in public. I find it more comfortable and also I'd just feel odd about not wearing it...As for polite, to each their own really, whatever you find most comfortable...
if you have barely any breasts and they are perky, it's not that bad. if you have more than a c cup though (not saying a b or c cup is barely any breasts!), it's REALLY awkward. at least for the girl. I imagine guys would love it. but girls will feel exposed, unsupported and like an animal in the zoo...
NOOO! PLEASE NO! I find that older women are doing this more and more, they just leave the house and are like whatever. When I say older I mean mid fifties to like seventies. Where they don't have young boobs, they have been through kids and gravity for years and years. Their boobs are at mid stomach and one women down to her bellybutton. You shouldn't do it even if you are young. I think it is inappropriate and tasteless. Me being a girl I know I do not want see your nipples and outline (what if it rains). Every woman should wear a bra unless the dress or top can not have one.
It depends on the place or time if you are going to get some groceries who cares if you wear a bra as long as you don't have boobs hanging everywhere but if you are makin a first impression put on a bra I prefer wearing no bra with backless dresses because showing your bra looks trashy but I also have fairly small boobs I guess it depends on the situation
i think a girl with small breasts (anything B cup or below) can get way with not wearing a bra in public in a tank, shirt or summer dress, especially if she is just out to run errands or get coffee, but I would be wary of a girl with ample breasts letting her goods hang out. I mean not only is it aesthetically provocative (in a bad way), but really it would be physically uncomfortable for the girl to have her boobs unsupported.
Personally I feel really conscious about it, I can feel that I'm not wearing one. I start thinking everyones staring at me, and noticing how "saggy" they are (I don't have saggy grandma boobs, just in comparison to wearing a bra, they droop obviously.
Also, for me it's really uncomfortable and a touch painful.. I have DD breasts so if I walk too quickly they bounce and hurt.
It looks a bit slutty and personally It's an eye sore . But like most women say if they have small boobs I guess It would not really look that bad. I understand that some women like to be more comfortable when wearing there clothes.
