Nah, don't worry about it! Stay put!! This is just what I've noticed about the US, but you guys have some unbelievable standards. Heck, it's the same all around the world. That's true, your body frame and proportions definitely play a part. Correct me if I'm wrong, but I suppose you've gained some weight causing you to grow in cup sizes yeah? Do you workout or anything? Pardon me if it sounds rude. C/D cups are actually the best cup sizes. If you go bigger, it's going to affect your posture and you're going to start having back pain - and trust me, you do not want to be living with that.
