BEST: Taylor Swift

The best way to get over a breakup? Looking even more amazing than ever! Fresh off her split with One Direction\'s Harry Styles, Swift foregoes her usual princess ensembles for a crisp white gown with a very sexy plunging neckline. And to top it off, she\'s already going home with a People\'s Choice award for Favorite Country Artist.
BEST: Lea Michele

Pretty in pink Elie Saab with matching heels, the "Glee" star shows off long legs, freshly tanned from a vacation in Hawaii with boyfriend and costar Cory Monteith.
WORST: Kaley Cuoco

The People\'s Choice Awards host may be sweet as a cupcake, but dressing up like one in this Christian Siriano gown wasn\'t the best of ideas.
BEST: Julianne Hough

The former "Dancing With the Stars" pro knows how to rock sequins. She sparkles in a Tony Ward Couture dress and silver Guiseppe Zanotti shoes. Alas, boyfriend Ryan Seacrest couldn\'t escort her down the red carpet due to an "American Idol" commitment.
WORST: Olivia Munn

While black and white is always a chic combination on the red carpet, the gorgeous "Newsroom" star looks positively frumpy in this ruffled number.
BEST: Chlo? Grace Moretz

Neon is so back! The cute-as-a-button "Kick Ass" starlet can probably be seen from outer space in this bright yellow Simone Rocha mini.
WORST: Kristin Kreuk

Did the "Beauty and the Beast" star get lost on the way to a winter formal? Though the peach gown is a lovely color on Kreuk, the sequined bottom paired with the frothy top looks a bit junior.
WORST: Ellen Pompeo

A fashion stylist, stat! Thankfully, the "Grey\'s Anatomy" doc left the scrubs at the set, but this loose white robe, cinched by a plain black leather belt, was D.O.A.
BEST: Heidi Klum

Hello, sexy mama! The "Project Runway" host may be a mother of four, but still knows how to vamp it up in a Julien McDonald black dress with slits across the body.
BEST: Naomi Watts

Princess Diana would approve. Watts, who will play the icon in a movie this year, is stunning in a dramatic black and gold backless gown.
WORST: Paris Hilton

So not hot. Where to start with Hilton\'s garish green-print minidress? The three bows? The Spiderman-esque top? The faux lace bottom? Maybe she was trying to be edgy, but this number just ended up hurting our eyes.
BEST: Ian Somerhalder

Let\'s face it, Somerhalder would look good in anything (and especially nothing at all!). But he is especially dapper in this classic black suit with skinny tie. And those piercing blue eyes are the evening\'s best accessory.
BEST: Chris Colfer

The "Glee" star proves you don\'t need a tux to be suave wearing a navy shirt, charcoal pinstripe trousers, and super skinny gray tie.
BEST: Brittany Snow

Looking like a fresh spring daffodil, Snow is "Pitch Perfect" in a elegantly draped Maria Lucia Hohen dress.
WORST: Morena Baccarin

The ravishing "Homeland" star would probably look good in a brown paper bag, but this bland, strapless white pantsuit isn\'t the most flattering thing she\'s ever worn.
