I seem to recall a movie with, I think, Quinn Cummings. I've been to IMDb and looked up her movies and can't find the one I'm looking for. It's probably from around 1980. Quinn, or whomever it was, accompanies her friend into the friends room, where the friend removes her top to change it. Basically seen from the back, but there may have been a bit of a side view. Because of my searching, I am starting to believe it was not Quinn Cummings.
