What would you think if someone arrived at a Halloween costume party nude but in full body paint?

If your all adults and the host is okay with it. I say go for it! I think an aquarium theme would be awesome. Paint yourself blue with some plants and lots of fish all over.

Whith undies it will look fab

iwouldnt mind if they were earing underwear

If it was one of those "fetish" parties then that happens all the time. But for your average adult-oriented halloween party, Im not sure some people will freak out. Make Sure there are absolutely no children anywhere near the building or in the neighborhood for that matter.

For a dude, how the hell can you cover up a penis?! And for a girl, how the hell can you cover up a vagina?! Penis would be harder, but still...that's an awesome idea, but it might be a little unsuccessful.

Umm, what if some guy's mom walked in with her five year old son and saw that. Don't you think that would be kinda...awkward?

I dont think that legal

I would think 'interesting, but he or she must be awfully cold.' Basically, I've seen that kind of thing before and it wouldn't bother me. I would try very hard not to stare at the person all night and I probably wouldn't feel very comfortable talking to that person, but to each his or her own.

It depends on the host and who will be present. It could be fine. They might get a little more touching than others but if they are happy with that then go ahead. The other option is to wear a small g string under the paint. Have a fun party.
