It depends on why one is wearing a bra. In the US, where the bra often essentially is the Western woman's veil, I suppose it makes sense to make girls wear a bra as soon as there are evident breasts - ie at Tanner stage 3. If the purpose is to hold in and support the breast, it's enough to start at Tanner stage 4 if the breasts are largish, and at Tanner stage 5 if they are smallish.
your choice. if you do wear a bra, wear a sports bra
If you need a bra, you should wear one.
yes she should wear a bra
a man should always wear a bra because their very comfortable.
When a girl should wear a bra is not based on a certain age. She should wear a bra when her breasts start showing.
stage 3 for sure
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.
I think you should wear a bra if they are getting bud i am 17 and when i was 9 i wore a starter bra if they dont want to wear a bra try a starter bra which would be best as i said earlier i am 17 and i wear a 38a
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.
When you just begin breast development, I would recommend either a training or sports bra. Neither has cups, and are there for comfort and so that darkened nipples don't show through shirts.
