I am the completely opposite - since putting back on 15kg (after my 30kg loss), one of the biggest things I've noticed is how bigger (and jigglier) my boobs have gotten and I HATE it.
I currently wear a size 16B, lol yeah I know a girl who is a B and complains about being too big, ha ha. When I was smaller I used to wear a 14B and was much happier. And I know that means that I lost a lot of weight around my back etc, but it also equates to a loss in the cup area. A B size in a 14 is smaller than a B size in a 16.
So I am definitely looking forward to dropping some weight off my chest area and getting my perky little B cups back
