Continuity mistake: In the scene when Lulu Bains is prancing around in the dressing room, there is one steady shot of her. In this shot, as she moves around, the right strap on her outfit begins to slip off her shoulder. The shot ends by her side with the strap completely down her mid-bicep; however, in the very next shot, which is from the front, her right strap is back up, and it's her left strap which is halfway down. The print wasn't reversed to this effect, either.
