I have to chime in here. Apparently some peoplewould be appalled at me, I wear a tank suit only for a water park. The rest of the time, my size 14/16 180 pound body is in a 2 piece. And at home, I only wear the bottoms. I am not in the least concerned if someone finds it horrifying that I, a 50 year old mother, wears a 2 piece suit. I don't wear thong suits, nor do I wear side tie bottoms, but my suits are all below the waist bottoms, and small enough tops to where I feel that I am covered, but not overly. That being said, Barb, if you want to wear a 2 piece, go for it. Enjoy the sun, you will probably need sun screen, as you won't have been out for a while, but don't let anyone tell you what you should or shouldn't do based on their outlook. Do what you want, because in the end, it's what will make you happy. BTW, my DH says he doesn't care, either, and if he did care, it doesn't sway me. He knows that I am comfortable with how I look.
Be happy Barb, by the time you get on the ship, you will have it all worked out, amd you can enjoy.
