text: ok im 15 an my bra size is 40d is it to soon to get a boob reduction? i hate big boobs? big boobs+the wohle school haveing little boobs=not me at 15 your still growing so i think its to soon. when you get older you may like having a bigger chest. are you over weight? if so you can work out and eat better and it might reduce it some. but be happy the way you are you could be stuck having no boobs. hey if your the only one in school with a big chest be proud of it, your one of a kind.
