Fashion Models was one of the more obscure games on the American version of Whose Line.
Fashion Models featured all four performers. One or two of them are commentators at a fashion show. The rest of the improvisors model the new clothes based on an audience-suggested profession. It's similar to Hey You Down There, with an announcer and actors.
Greg Proops usually takes center stage as the commentator, though the first time it was played, Denny Siegel was a commentator as well. That time, based on wrestling fashions, had a memorable exchange between the two:
Denny: I love wrestling because it's the only sport that proves women aren't the only ones to fake it. Greg: And no one cares if they do.
Brad Sherwood also occassionally took the role of commentator.
