In the films Ciao to Radik and Adam's new apartment we see a large group of young people partying nude as if it were the norm and what's more apparently agreed to be filmed. I don't know what country these films were made in, but where do you get a group of young people like this that comfortable with nudity. I think it's wonderful, but how common is it really in these countries? I'm just curious about the back story of these films.
