Amber Riley (Mercedes) is mostly limited to ensembles of the jeans-and-sneaks variety on Glee (albeit with a ton of funky flair), but her gorgeous look in Glamour's May 2010 issue shows she can also get dressed up and look fantastic doing it. In exaggeratedly perforated Dior heels and a Tadashi Shoji ruched one-shoulder frock, Amber confesses to being a "colorful girl," and we wouldn't have it any other way.
