What size depends on what size her breasts are. if she has none she doesn't need any. Ask the lady in the store to help you because girls are all different.
No wait until they get bigger no use in wearing a bra I say.
well for one, get some help. Why were you wearing a bra in the first place?
A 12 year old girl, should be wearing a none padded bra, that fits her boobs the right way. Make sure they are right for your skin and pick the right pattern!
depends on your age
you should wear one if your breast are big enough I started wearing a training bra at age 7 to get used to it I actually needed it at age 8 and a half and I started wearing size 36A at age 9 I am now 13 and wear size 38C and my mom says I'm almost ready for a 32D so really any age but defiantly in 6th grade you should start wearing a cup bra I started wearing a training bra at 7. I got my first cup bra at 8. I'm 13 now and I'm a size 36DD. By the end of your 5th grade year you should definatly be wearing a cupped bra.
if you wear a bra in the day its ok but wearing one in the night can mishape your boobs
Wait. She does not want her friends to tease her. In a year she will have a reason to wear one and they will not tease her. Let her be a kid for another year. When her friends start teasing her about not wearing one, she will start.
When your breasts start developing you should start wearing crop tops/training bras. Once you have developed large enough to fit into an A cup, you should wear a proper bra.
Probably a sport bra, and one that is your size.
I think it should be when you have a 'chest' and you need one. I need to start wearing one and I'm 10.
age doesn't matter. some are 8 some are14 be4 the start wearing bras. all my friends and peers where bras but i don't because i don't exactly need one even though im 12 my and my friend are the same age. if you are under 10 or under and need a bra i think you should wear a sports bra they work good and people wont stare at you. if you are 11 or older and need a bra i say go a head a get a cup bra. they start in a super small size and go to super huge. there is no rule when to start wearing a bra in Canada but basically when ever you need one and are comfortable wearing one. if U aren't comfortable wearing 1 but U you need you should wear a sports bra no matter what age u are. a sport bra is very comfortable. Hope this helps! source: experience from a 12 year old
NEVER!!!! you cant get any cancer by wearing a bra!
