If you like to wear Bras, you should wear a bra. If there is some reason that you don't think you should (such as if your mom says you're too young or you're a boy who knows it's socially unpopular), then balance other people's opinions with your feelings. It might be worth not wearing a bra for awhile, or it might be a better choice to wear the bra anyway.
If you need a bra, you should wear one.
yes she should wear a bra
If your bra makes it hard to breath in, you should wear a larger band size bra. If your boobs don't fit in the cups of your bra, you should wear a larger cup size.
It depends on your opinion. If you feel like your breasts are small then maybe you should. but if you like your breast size then don't. i wear a puffy bra myself and it doesnt hurt you in anyway.
for the craic
yes you should
A baby should not wear a bra. It would be bad for their growth and support to wear a constricting piece of clothing.
This is a very personal choice. If you feel that you need the support, you should wear a real bra. If you are comfortable without a bra, or comfortable in a sports or training bra, you should stick with that so long as it is appropriate for your work or school.
Sometines it will look good like a layered look or just buy a strapless bra for a better look
no
You should either wear a bra once your breasts are large enough to be pulled down by gravity, or choose not to wear a bra and have breasts down to your waistband when you get 20 years older.
You should wear it if you don't want to show your bra it may sound unusual but it the bra won't show.
