I so wish I had this "problem". I am a 44 DD, VERY big breasts and I Can tell ya, having big boobs is not fun...I can only wear a few shirts, and it is embarrassing to go clothes shopping...I need a reduction!!
If I could I would give you some of mine!!! hahaha But seriously, go ahead and do it. Just make sure it won't set you too far back financially and make sure to do alot of research!! If you have a small frame, then I would go with something like a large B or a small C. If you're a curvier, big bum, bigger shoulders, I would go with a medium to a large C...but that's pushing it. Trust me, it will be alot different, but if you think that's whats right for your body, then do it...don't go too big for your body, but just enough to "fill out".
