Where can I find films with women taking clothes off and walking naked at home?

Also, I'm searching for a film I saw in an old forum: a girl is in some place like a board college, changing clothes to go to swimming pool. Then she decides to go naked and, when she comes to the pool, some other girls follow suit and takes off their swimsuits. Anyone knows the name or can help me to find it?

Thanks in advamce.
