Do the dancers get fully nude onstage or just with private dances

I don't believe they do.

Some do. The last time I was there was last year for a UFC event. Like maybe a 1/6 of the girls got fully nude, at the most. I don't go enough to really notice, but my friend made a big deal about it that night so I took notice.

In general, no. IME rarely.

Just to refresh this question. It depends on the dancer. Some will do it gladly and very appreciative mind you. But some will lead you on trying to get you hot and ready for a VIP/CR where they say they’ll oblige nudes.
