I don't know about "should", that's very much a cultural thing. But a bra give some support and prevents the breasts from bumping around when the girl move. Particularly women with heavier breasts appreciate that support.
actually that is not the reason they should because if you don't then later in life you boobs will go saggy like my old teacher she didn't wear bra's when she was like 11 so now her boobs go farther than her belly button true story her name is mrs.cambell
It depends on whoo you are! I'm 12 and I do
No
Girls usually just wear whatever size they are. If they wear smaller bras, it generally has something to do with them having a smaller body.
well of course girls wear bras they are MADE for girls and women
Sometimes girls don't wear bras because their boobs hurt or they are just having a lazy day.. LoL
No. Definitely not.
We wear bras so our nipples dont show through our shirts
It is logic for girls to wear cup shaped bras to cope with shape of their breasts.
Girls don't have to wear bras - many girls do because they feel more comfortable, girls with larger breasts may need the additional support, but no one HAS to wear bras if they don't want to.
all the girls
Depends , but if it is a cup bra, no. Usually when kids start to wear bras they wear sports bras, so that's what they should sleep in.
We don't HAVE to wear bras. Some women don't. It just depends on the women. Some wear bras because they like it. Some aren't comfortable so they don't.
