on average between 30A and 32B.
I am a 11 year old girl and I have no boobs. So really the average size is none. I only have breast buds.
34 b
32A or 34A would be average bra size for a 12 year old girl.
34B
b or c
There is no average since each girl/woman is different and breast size is based on DNA.
1 cm
The average size is a 32 A or 34 A but if you are bigger or smaller its just how your body is growing
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.
Everybody is totally and completely different.
AAA
