I did this one year!
Just take an old sheet & sew up the sides, use some type of wire to form the top into a circle & pinch the end into the same shapes as the top & bottom of a tube of toothpaste. With fabric paint or a marker or whatever write toothpaste down the length of the front of the tube. Top with a lampshade as the toothpaste cap.
Or how about a bunch of grapes?
wear a body stocking & attach balloons all over your body? Only problem with that one is you can't sit down.
Gotta love that nudist on strike though
