Eek! Emma Thompson's stylist should be ashamed for letting her wear a dress that is three cup sizes too large.

We get why Jennifer Love Hewitt chopped off her hair post-break-up, but that's a lot whole lot of volume for a tiny little face. And where's she going in that long-sleeved, sequin wrap dress? Studio 54?

Madeline Zima is a vision of beauty in this bright red, low-cut dress. And we love those sexy leopard peep-toes.

Jessica Alba needs to do three things: Brush her hair, find a bag that matches her dress and burn those shoes.

The jeans and black blazer are fine, but what's with Brad Pitt's hat and dirty-looking goatee?

The simple silhouette of Kristin Chenoweth's blue and black strapless dress is cute and classy on her petite frame.

While it's nice to see Janet Jackson beaming, baggie capris paired with her long jacket fail to flatter her hips.

Gray is too blah of a color for Rachel Weisz, and the dress itself is just plain boring.

We love how well the white and ivory of Kim Cattrall's one-shoulder minidress work together. Simply beautiful.

Sorry, America Ferrera. Belt or no belt, a jumpsuit is still a jumpsuit and should never be worn on the red carpet — period.

Bright colors work great with Teri Hatcher's dark hair, but that miscellaneous piece of fabric hanging from her waist doesn't look right.

Pauley Perrette's black cuffs are the perfect accessory for her shimmering black dress with tied straps.

Ginnifer Goodwin's sheer red dress is too matronly for someone her age — and we're not crazy about that collared neck, either.

Kelly Carlson looks amazing with black hair, but her long black dress is too Elvira for our taste.

Aston Kutcher and Demi Moore always seem to nail it on the red carpet, and this pairing is no exception. We particularly love Moore's structured balloon skirt.

Everything from Lea Thompson's white-trimmed pumps to her matching dress is just screaming '80s — as in dated.

Katie Cassidy's black and silver dress fits her perfectly, but the blah gray shoes knock the overall look down a few notches.

Kristen Stewart's silver and gold dress is fresh and funky, but it somehow doesn't seem right on her — it's almost uncomfortable to look at!

On anyone else, this jersey dress would look like a giant Ace bandage, but somehow Jennifer Aniston makes it work.

Amanda Seyfried looks great in an asymmetrical blue dress, but what was Julianne Moore thinking pairing black tights and boots with pastel pink?

While the clustered butterfly pattern on Alicia Keys' black and red dress is fun, the cut is not flattering.

Alan Cumming's baby-blue checkered suit is poor man's Pee-wee.

The 5-foot-2 Eva Longoria looks positively statuesque in a red, one-shouldered gown with a long train.

Kelly Osbourne looks spectacular in this pink, long, feathered gown. But what's with the purple Dame Edna hair?

Ugly Betty's America Ferrera is far from ugly in a gold minidress with a bubble skirt silhouette.

There's really nothing special about Debi Mazar's black and red floral dress. And the giant feather in her updo is not attractive.

Lea Michele shows off her amazing figure in a black mermaid gown, but the overall look is too mature for her age.

A copper-toned draped gown would have looked nice on Hayden Panettiere when she was a blonde, but it's just too matchy-matchy with her new hair color.

Heidi Klum looks youthful in this black satin minidress with thick silver trim, but her make-up seems to wash out her features.

Michelle Rodriguez looks lovely in a bright, ruched gown.

From the exquisite fit to the subtle pattern, Victoria Beckham's dress wins for understated beauty.

Eek! It looks like Salma Hayek spun her head around 180 degrees and is wearing her rear end in the front. And those shoes? For shame, Salma!

Wow! Jennifer Hudson is a total knockout in this stunning navy, floor-length gown.

Terri Seymour's stark white gown with gold embellishment is a little too flimsy for anywhere other than the bedroom.

Demi Moore looks extremely sleek and elegant in a long, flowing cobalt dress. And we love her colorful clutch.

Some would call Kelly Rowland's black minidress with blue leopard accents high fashion, but we prefer to call it just plain ugly.

Marisa Tomei's black minidress with a strappy halter neckline is just screaming '80s streetwalker.

Vivica A. Fox is radiant in a sparking black v-neck dress with a chain-belted waist.

Wow. We almost didn't recognize Renee Zellweger in this photo. The overall look is just a bit too severe for our taste.

Sisters Tia and Tamera Mowry bring double the style on the red carpet. Tamera (L) is ready for spring in her yellow halter and colorful skirt, and Tia (R) is super-chic in her gray, one-sleeved minidress.

Reese Witherspoon looks stunning in a deep purple minidress with a black-belted waist.

The texture of Angie Harmon's sheer overlaid dress is quite elegant, but the fit is a bit frumpy.

The volume of Rachel Zoe's black-and-white petaled dress really works wonders on her.

We get that the whole unkempt look is part of Robert Pattinson's shtick, but could he have at least finished buttoning his shirt?

Kristen Stewart's skin-tight gold pants paired with a black leather jacket is not a cute combo.

It appears as though Emilie de Ravin pulled up her dress and pinned it to form some sort of diaper look.
