I think I might be getting paranoid?

First off, I am trying to go behind my wifes back here, this is somthing that we have actully talked about. Just looking for some advice, Me and her are going to Flordia this summer, on vacation. I love my wife very much and I think she is very beautiful. With that being said she wants to wear a thong bikini to the beaches. Dont get me wrong I think it would be very hot for her to do that. But she does have thicker thighs and a much lager butt, than most females you would see in them. She has already bought the bikini and she looks awsome in it, but it is very skimpy, pratically her whole but will be showing. I guess Im just concerned there would be some A hole that would make a comment. Is this somthing that would not be socailly acceptable? Or am I just being paranoid?
