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.
depends on your age
if you wear a bra in the day its ok but wearing one in the night can mishape your boobs
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.
IF she needs one. Otherwise, no.
NEVER!!!! you cant get any cancer by wearing a bra!
There is no size, it all depends on comfort. When you get to the point that you are more comfortable wearing a bra than you are without one you should start wearing one.
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.
You are probley a child typing this, but i started wearing a bra when i was 8. You can wear a bra when ever just dont buy one that is to big or to small. You shoulld let her wear a bra if she has a smaller chest concider a size 30A or a sports bra.
if you re afraid you are showing your nipples through your shirt than you should start to wear a training bra.
You should start wearing a padded bra whenever you feel comfortable. Of course you would ask your mum first and see what she thinks of the whole idea and if she thinks your big enough. hope this helps xx happy bra shopping xx
