Are you "really" asking what to "wear" to a nudist resort? Chris is correct. I just thought it funny that you asked what to wear. It is a really nice place, I hope you enjoy.
Typically whatever is comfortable, and what will keep you warm when the temp inevitably drops. The only clothing-banned location is the pool area and nobody will look at you sideways if you're clothed, but you will probably feel out of place and honestly, you're paying money not to so why bother?
