Major Makeovers

From day one, everything about Carrie said "small town girl." She was already working with a full deck of cards; she just had to learn how to play 'em. Flashing that winning smile and adding a little "come hither" helped her redefine her image.

Justin Guarini

Comparisons to Sideshow Bob aside, Justin had a pretty decent sense of style -- minus the one or two times he tried to pull off wearing a muscle shirt. And thankfully, he's dealt with his addiction to pleather.

Kelly Clarkson

Die-hard fans will remember that Kelly auditioned in a homemade denim dress and had tussled hair. The formerly unpolished theater concession stand worker donned her first hair extensions during the 'Idol' finale and hasn't looked back since.

Tamyra Gray

She started off as the unassuming "girl next door" and ended up as the vampy vixen with the vocals to match. The key to Tamyra's new look was to let it all hang loose, trading the safe style choices for something more daring and eye-catching.

Jennifer Hudson

Jennifer Hudson was once a victim of her own eccentric style, with weird eye makeup and dreadful outfits. But she came face-to-face with her fashion faux pas and has emerged a stunning beauty, letting us know that she's 'Idol' no more, but a 'Dreamgirl.'

Katharine McPhee

We've definitely got a "McPheever." During the Top 24 performances, Katharine often sported the T-shirt and jeans look. But when a possible victory got in her sight, she quickly learned to bring her A-game. She found designer dresses, high-end shoes and big earrings to match her big voice.

John Stevens

Starting off, John looked like a younger version of Conan O'Brien, but his transformation stayed true to his crooner roots. He stuck to high-end suits and slicked up his red locks to create a new look.

Taylor Hicks

Taylor was a stylist's nightmare. He was dressed like he was ready to pick up the kids from soccer -- he wasn't even 30 years old -- and had a full head of gray. But he lost weight, got some new threads and made good on his new rock star status.

Jim Verraros

Jim's full transformation didn't happen until he was kicked off the show. After coming out of the closet and landing an indie record deal, he got himself all glammed up -- flat ironing his hair and going sans specs.

Clay Aiken

It was the biggest transformation of them all: Clay's gradual progression from sissy to stud. (We're being kind.) The self-professed "dork" lightened his hair, gained a little weight and threw on some designer duds to complete the look.
