Everyone loves a good show tune, but sometimes when it comes to musical theater, what we really obsess over are the costumes. We asked Shannon Mullen of the national tour of Rock of Ages to showcase her fabulous '80s glam. Click on the photo gallery below to see Mullen strut her stuff in her L.A. duds as Sherrie, a small-town girl who moves to Hollywood in search of her dream. Find out which outfit is her favorite, the one that makes her feel the sexiest and which costume she needs to slip into in under 30 seconds. Check out the rock ‘n’ roll looks, then get tickets to see Rock of Ages, which plays the Centennial Concert Hall from December 11 through December 13.
