I'm almost 15 and I don't know if it's just me but a lot of people have bigger breasts than I do. I want them to grow but I'm curious for most people when do their breasts get biggest? At what age? I'm still like a 32A and I wear a lot of push up bras.. I heard a rumor that its best to wear looser bras to help breasts grow larger? Please let me know! Thanks:)

Look at your mother's breasts. Are they large or small? Breast size is genetic.

Breasts actually continue to develop until around the age of 21.
