You go to the party clothes, strip off in a room alone and then enter the party. You cannot dress again until leaving the party hours later

its always been kind of a fantasy, as it can develop into all sorts of interesting senarios.

I have always wanted to do this. I’ve wanted to be a naked waiter or servant at a party

The first option. You go to the party, get really drunk, and then strip and be naked. I couldn't be naked in front of so many other people naked.

Go naked. Easier to explain and then get dressed after a couple minutes.

How exactly would you explain it?

If I'd be nude at the party, the crowd would notice immediately, so later it really wouldn't matter if i get dressed again or not, at least I'd na naked only at the party and not on the street.

I think I would prefer to strip naked on the set. If entering naked is the option then I'd pick that.
