A note about wetsuits.
I once worked on a show where people were in wetsuits as the base layer for a costume not entirely dissimilar to this; we had people collapsing through heat exhaustion, and even those who didn't had to unzip every twenty minutes to release the niagara of sweat. It was most horrible, especially after the third or fourth day (I won't give any more detail in case anyone's eating, but anything foul that you can imagine about this situation is probably true).
Neoprene looks great and avoids the skimpy "dancewear" look, but beware high temperature.
