Come and be my belly dancer

Last night I was at a SC and noticed nearly every girl had their stomachs clothed. Even during private dances they would lower their tops to reveal their breasts but when I asked her to take the whole thing off she said no she wants to leave it on.
I know some are doing it to hide marks from their pregnancy, and others are trying to cover up their beer gut, but it surprised me that nearly every single one had it covered. I actually got aroused when I saw one dancer wearing a normal bikini without her belly covered. This was at Club X (a top 100 tuscl club). I wonder if this is a fashion trend or if the dancer quality in Ohio has been reaching new lows lately.
