Where I live in Israel where even where Moslems are more liberated to some extent of the guidelines relating to Modesty, a young Moslem women show shows up in a bathing suit that "reveals skin" is off-sides. I didn't see her, but some Moslems might not be as proud, and tell you that a decent Believer doesn't go around "half naked".
All right, standards of modesty have changed, and even Gypsy Rose Lee wore a G-string and pasties--and that was called strip tease! Today you get that on the Fashion Channel as nothing special.
I guess it's a sign of the times that American-born Moslem women are not concerned about how they dress in public, maybe the young,men don't mind letting people know the brand of of their underwear, too.
