During the scene when Sandy and Danny are in the malt shop and the Pink Ladies and T-Birds are gathering around the table, Rizzo is holding her compact in her left hand and a cigarette in between her left index and fore fingers while applying the contents in the compact with her right hand(this can be seen in a wide angle shot). Then, in a close-up, she has switched the cigarette to her right hand while putting on the make-up. I could not see any break in the different shots.
