Oh, my, evidently (ads seen) it is time to go get a swim suit. If you need "permission", well, I say you may do so. Or go nekked, up to you. A swimsuit, if I understand History, was a garment meant to cover the bod from whatever point to whatever point that the social system said should be covered in whatever year that was, like 1900 or 1920 or 1940 or 1960. So you wouldn't BE nekked or get your street clothes wet. After 1960 or so, things went to pieces. Pun, pun, but true. Went to smaller and smaller pieces. By 2000, underwear and bathing suits looked pretty much the same except for the cloth or whatever it was made of, a patch and some strings. I suspect you could wear your underwear and no one would really notice it wasn't a bathing suit.
