July 14 is “International Nude Day”, and if you’re in upstate New York, you can take a clothing optional tour of Howe Caverns. You won’t be TOTALLY nude though; Socks and shoes are required, because, you know, it’s a cave.
body paint clothing is a workable compromise for exactly those situations. Fully nude and fully clothed! It works for me on the World Naked Bike Rides.
