Katharine McPhee's Red Carpet Style Evolution

Our February cover girl, Katharine McPhee, has come a long way since being named American Idol's fifth season runner-up. She's released three albums, starred opposite Anna Faris in The House Bunny (one of those feel-good comedies we can't help but watch every single time it airs) and established herself as a bona fide TV superstar with a leading role on NBC's Smash. And as her star has risen, Katharine's also stepped up her style game, trading bootcut jeans and super-short minidresses for glamorous gowns by Donna Karan and Dolce & Gabbana. Click through to witness just how dramatically her look has evolved over the past six years.

Back in her American Idol days, Katharine was all about flared denim and "going-out tops." Cute and youthful, sure—but not quite worthy of her killer voice and fab figure.
