If you wear a bra that's either a little bit big or a little too small, will
it cause your chest to not grow? – Gilly*
No. A girl's bra won't affect the growth of her breasts. That's
because genes and hormones control breast growth, not what a girl wears.
Bras don't make breasts grow or stop growing, but wearing the right-size bra may
help you feel more comfortable. Bras that are too small may cause breast pain because
of how sensitive some girls' breasts can be as they grow. And bras that are too big
won't offer enough support, which could also lead to discomfort if your breasts
move or bounce around too much. Find a bra that's the right size for you and
comfortable to wear.
Want your breasts to develop the way nature intended? Eat a variety of healthy
foods and exercise regularly. And don't worry if you don't develop at the same rate
as your friends. Some girls develop earlier, others later. A girl's breasts can keep
growing and changing into her late teens.
