Almost everyone I know that lose weight, find their breasts growing smaller as they lose weight.

And almost everyone I know that put on weight, find their breasts growing bigger as they put on weight.

Do a search next time.

You shouldn't be considering having a breast enlargement done, it's more important to be healthy and comfortable than having big boobs to please the bf.

Actually, small boobs are great. If the boobs doesn't match our body size, we will find it hard to find tops that will fit us nicely.

Smaller boobs also means less weight, doing sports and everyday activities is much easier. It's lighter and more convenient. And if you want the cleavage and all that, just get a good push up bra, a low cut top and you're good to go. What's also important is our posture. Even if you have big boobs but you hunched then your body won't look good at all.

Oh and I find bras for smaller cups are much nicer, especially bras with french cup. The big cups one all looks quite old fashion only.

I'm happy with a comfortable and natural size and there's no need to grow the breasts bigger. Unless you are completely flat like the girl in the YouTube video in the other thread then its understandable.
