I think they speak French in this movie, it’s either from France or Canada. Possibly an independant film. There’s a scene where the girl is dancing in her bedroom, and she knows there are people peeking through the window (possibly her ‘friends’). So she puts on a green top hat and really makes it a show, starts stripping. The music is upbeat, she is twirling around and jumping around. Continues to strip but leaves her shorts on, holding up a sign to the window (can’t remember what it says), waves goodbye and quickly closes the curtains. Later on in the movie she is seen with the same friends, smoking a cigarette on the couch, then later she and these friends are swimming.
