The challenge is after the party remove all the paint to go to bed lol.
I attending a resort Halloween Party a number of years ago and a few guys came as the Blue Man Group. After they won the costume contest they used the resorts outdoor showers to wash off the paint and left a blue mess. The owners were pissed.
We don't quite celebrate Halloween where I live , but the present generation who look to aping the west , try to organize this event. I was once asked by a nudist friend from abroad to give him costume suggestions based on movie themes for a nudist Halloween party and I came up with these. THE WIZARD OF GAUZE , wrapped loosely in gauze bandages, witch's hat and a cellophane bauble to act as a crystal ball covering his bits. THE CANDY MAN with balls painted in bright colours to represent gum balls , penis painted black as a licorice stick, nipples dark brown as Hershey's kisses, pink powder dusted on the pubes for candy floss, white circle around the navel for a peppermint ring and a couple of sweet wrappers stuck around here and there. :)
