Ok. So i'm 13 and i'm a 34D. I feel like I'm way too big. All the guys in my grade are always staring at my chest. I know some women would kill to have a chest like mine, but how can I dress to make them look smaller???
I was like you at 13 and my advice to you is get a GOOD bra. One that will support you. No matter what you wear , your boobs will show, so don't make yourself look worse by wearing baggy tops. That will make you look fat or pregnant. Embrace your curves as best as you can and go get a really good bra.
