It varies between a 7.5 and a 10 usually.
size 12 or 14
A 10 year old girl would likely wear a size 10 to 12. This is just average though, some will wear bigger and some will wear smaller.
It depends how large that 5 year old is. Kinda like asking what size shoe do men wear ?
usually about size 3 or 4.
A 7 year old boy might wear a size 1 shoe, or he might wear a size 13. Some 7 year old boys with very large feet might even wear a size 2 or 3 shoe.
Should wear 7/8 or meduim
There is no particular size for 15 year old girl's to wear. Every girl is different in size and therefore you should get measured. If you go into shops like Debenhams or La Senza, they will measure your size for free and make sure you are wearing the correct size of bra. i think any size will do if it works for ex) i know a 12 year old size c and another 20 size b
no more than a 16
A 12-year old girl should wear a size 12/14. If the girl is tall, she may want to go up a size so things will fit better.
It depends on the size of the 12-year-old girl.
10 year old girls are not really supposed to be wearing any kind of cup size.It's best to wear training bras or sports bras...But if a 10 year old were to wear a cup size it would probably be a 32AA...11,12 and further that's when you really start to wear a cup size.
Well, if your shoe size is seven, then you can physically wear them. However, it is uncommon to have that shoe size at that age (it is possible though).
