Well, if I ever get back into shape (which I'm working on) I'd consider it. Especially since the closest beach to me is Rocky Point and I know that no one there would mind such bathing suits. At normal beaches I probably wouldn't wear something like that but at some of the more "spring break" or nude beaches I would definately give it a try.
And of course if I end up building a pool into my house, I'm sure the SO would love to come home to that scene
I agree that most of that stuff doesn't look the least bit comfortable but at least I don't have big breasts so I don't really have to worry about them falling out of the top!
