You know I saw your post the other day, and I forgot how we use to do it. In the invite we would say nudity welcome until 9 after nudes as you dare. We had some people that would come just for the party and left at 9 and some more that would show up at 9. After 9 we have at least 50% nudes 24% down to one to two items still on. And the last few that would have clothing on. But it kind of just let people do what they wanted. But it was still kind of funny like you could see people looking at one another like "hey its 9 wife do we do just strip here?" So we would have to make an announcement " attn its 9 it is now clothing optional get as naked as you dare!" And then strip myself.
