The designers are asked to re-style the outfits of 12 women, all of whom have lost a significant amount of weight. Standing on the runway in clothes that are much too big, the woman are paired off with a designer.   All is going well, until Jack reveals that he has developed a staph infection in his face, and must leave the competition. The shell-shocked designers are discombobulated further by news that previously-auf'd designer Chris March will return to the competition.   In the end, Christian's two-piece design wins the competition, while Steven goes home for "turning a wedding dress into a funeral dress."

Project Runway went back to high school this week as the designers helped their student models get ready for prom -- one of the most important nights in a girl's life, as Heidi says. All of the designers had to work with their teen clients -- and clients' mothers -- on their concepts, and while most didn't have a problem, Christian found his client to be rather difficult, and let the judges know.   Other designers, like Rami and Ricki, may have been confident in their designs, but the judges weren't too keen on them. In the end, Christian's inability to take charge put him in the bottom two, but the judges found that Kevin's too-mature red dress should send him home instead.   The judges, including guest judge Gilles Mendel, found Victorya's short blue sheath and Sweet P's long champagne ensemble the most appropriate, and the win went to Victorya.
