B
the average size is a b cup or a c cup
Today it would be DD cup, once considered large now more the average.
a C cup i believe
There is no such thing as a normal bra size for a girl of any age, even a girl who is 24 years old. Bra sizes between females vary according to their weight and body shape. The cup sizes C and D seem to be very popular in most stores.
It has increased in size over the years to accommodate more names.
could be anything but most are about an aa/a cup to a b cup
I would say depending if they are of average weight, a B or C cup. The more they weigh they larger their cup size will be.
There really isn't an "average" size bra for a ceratin age group. Most girls, however, are about a A- to a B-Cup by the time they are 13 years old. Still, it is normal for a girl to be smaller or bigger than that.
It depends on your family history and weight/size. For example if your on the skinnier size you probably won't be very developed. But that is completely okay! If your on the chubbier side you could be a larger cup size. If I were to pick an average cup size it would probably be 30A-38A for an 11 year old girl.
there is no average size for a girl. Some girls can be very flat and some very big. Usually anywhere from A cup to D cup. hope this helps!
Bras is something you have to go and try out. You have to learn what cup size you are.
That depends on the size of the girls breast and chest measurments.
