If the Dress Fits, Wear It is the tenth episode of The Cosby Show's fifth season which was first broadcast on December 8, 1988.


Clair hopes an exercise instructor, known as "The Bonecrusher", will help her fit into her old evening gown. Clair throws herself into the workouts, but her efforts are undermined by a mischievous Cliff. It seems he is so upset that she has not told him about her plan to lose five pounds in a week that he will pull every underhanded trick in his book to "test" her willpower – including the ultimate temptation: guacamole and corn chips!
