Just wanted to add - My wife tried out the pole in the SkyBar and noted that it is way thicker than what she's used to at pole classes. She was still able to climb it, but couldn't do anything flashy and found it pretty uncomfortable. The SkyBar itself is still an awesome place with an amazing view, relaxed atmosphere, an expanded food menu, and hot tubs that get a little warmer than the one by the sexy pool. I would advise against paying the admission price just to use the pole, though.
Sheer will definitely be sexy but what about crotchless body stockings? Has anyone been daring enough for that or is that over the line? I figure there are lots of short dresses as well with no underwear and there are probably lots of goodies hanging out.
