Good points Imckenzie. However, as far as the Linda Lovelace thing. If I recall correctly there were a few interesting wardrobe choices in both "Deep Throat", and "Beyond The Green Door", so the seventies skin schlock did have it's more cheezy side - lol. Could be just a matter of perception and personal taste though. What's funky to one person is mundane to another.
I think 1980s mainstream films are better examples of the much wider use of "WHORE CLOTHES", lol.
