No bikinis here, either. I don't mind two pieces but my idea of a two piece is a tankini and rash guard shorts. I prefer they are more modest in their attire, both swimming and living daily life.
I never had a problem as a kid going pee in a one piece, and one pieces were all I wore. Doesn't anyone know the secret of pulling the crotch panel off to the side and peeing that way? You don't have to take the whole suit off. LOL!
My kid won't do that. she freaks out b/c "we don't pee with clothes on!"
