Congrats on find a suit that you are happy with! I haven't owned a swim suit in years. I'm afraid of swim suit shopping! You are a braver woman than I am!
Sorry to be a downer, but I think most of the time cellulite is genetic and there's nothing that you can about it (aside from surgery.) Yes, some of it may go away with weight loss, but it'll never go away completely. At least this is true in my case. I had it when I was thin and when I was heavy and I still have it, so does my sister, so did my Mom. Most of the women I know have the same problem, so I've just come to accept that it's okay and very normal to have cellulite.
Time to lose the baby weight!
