We met a lady in January that was wearing crotchless fishnet boy shorts at the sexy pool with no problems.
Maybe just an overzealous Titti Guard. Who knows? It was really no big deal and she did try to arrange things better.
So what about a sheer or semi-sheer top that you can see nipples thru? That counts as nipples covered, I wonder? This is probably going to be a high proportion of CCC women on sheer night. Given that it's "sheer" night.
