Hayden Panettiere looks fabulous in her simple white one-shoulder mini-dress, but there's no need for those clunky winter shoes at the beginning of July.

Kathy Lee Gifford sets a bad example for daughter Cassidy. The fourth-hour Today host looks like she's rolled out of bed in her nightshirt.

The boy wizard may seem stiff as a wand in this pic, but Harry Potter star Daniel Radcliffe still looks mighty sharp at his London movie premiere in his beige suit and pink pocket square.

Between the polka-dot tights, gold shoes and tulle spilling out from under her skirt, it's hard to say what's going on with Helena Bonham Carter's ensemble. Perhaps she's trying to capture the mentally unstable look in honor of her Harry Potter character, Bellatrix Lestrange?

My, how Emma Watson has grown! The Harry Potter starlet looks superb at the movie's London premiere with her flowing, floor-length dress and plunging neckline. Fun fact: Watson had a bit of a wardrobe malfunction that showed off her knickers. But she made a good point to David Letterman: "At least I was wearing underwear."

Megan Fox could wear a garbage bag and still look hot, but this one-shoulder, clinging dress definitely made heads turn.

While the shape of Cate Blanchett's dress is flattering, the huge, oriental pattern makes her look more like a tapestry than an A-lister.

Dancing with the Stars co-host Samantha Harris wears a dress with a beautiful floor-sweeping, flowy feel, but the pattern may give you vertigo.

Taylor Momsen's got legs, and she definitely knows how to use them! The Gossip Girl star looks super-hot in her trendy high-waisted suspender shorts and black strappy heels.

While the bold black necklace and aquatic blue color looks great on Kristen Davis, the pattern gives us the urge to dive into her torso.
