Forgive my relative ignorance, but are those not called "moobs"?

Back to the topic at hand, breasts don't make a woman. Take it from a decent guy, that if your fiance truly loves YOU, he will love your breasts just as much now as he did before, if not more because you've gotten rid of some unhealthy weight. You are who you are, and if he's worth marrying, your cup size is the last thing on his mind. That's how I am.
