I can completely sympathize with you. I'm leaving in about 8 days. I bought 4 different bathing suits and only one ended up being really good. It's one of those "tankini's" from Lane Bryant. It looks like a tank top and shorts and it's very very comfortable. I'm not nearly as nervous now but I have to admit I will feel akward being around all those string bikinis. I'm sailing with my male friend and he's very trim and fit. I would suggest just wearing the things you look and feel good in...ignore the other people and enjoy. What an amazing chance to enjoy the tropics!! Have a great time!
