We would not think to pair this Thakoon dress with aqua metallic Jimmy Choo shoes, but Diane Kruger carries it off.

Christina Aguilera is not going to win any style awards any time soon, but this pared-down look is a huge step in the right direction. The natural-look makeup alone is a revelation.

The dress is pretty and fits well, and the crimson shoes are a great accent. But this odd length effectively shortens Christina Hendricks' legs by a foot.

Ice blue and white are just so pretty on January Jones. But we could do without the sheer "I'm an ice-dancer" element.

We like Elisabeth Moss so much in this sexy Alexander McQueen dress that we're pretending her hair looks better.

Holy linebacker! This dress does Julia Ormond no favors, imparting a top-heavy feel that doesn't reflect her actual dimensions.

We like the striking graphic look of Cobie Smulders's dress, but the '70s era prom shoes leave us cold.

Lena Headey shows off a great spring look in this striped dress, little jacket, bare legs and booties. The shades of salmon are a great way to add pizazz to black and white neutrals.

We like the color combination of navy and black on Sophie Turner. The asymmetrical hem and mixed textiles add interest to an otherwise basic sheath dress.

This dress is a little too Beverly Hills Housewife for 15 years young Maisie Williams.

Selena Gomez looks pretty in red, but it seems a little over the top — more Emmy Awards than movie premiere. And we'll never be fans of illusion netting.

Bella Thorne is ready for spring in this lively pink floral dress and edgy studded T-straps.

Vanessa Hudgens takes the Spring Break theme too far with this hula skirt look.

Eva Mendes' Peeps-colored dress is already a problem, but it's made worse by the fashion non sequitur of burgundy velvet shoes.

Is Jim Carrey trying to be funny? We're not laughing. This silver jacquard jacket looks like an '80s prom leftover, and he lacks the cool factor to pull off these shoes.

Considering she usually shows up dressed a whole lot like her Big Bang Theory character, Mayim Bialik looks surprisingly pulled together here. She's even wearing snakeskin shoes. Fashion-y!

The doily pattern on Beth Behrs' dress looks like a craft project gone awry.

Katie Couric is party on the top and business on the bottom as she oddly pairs a tough-girl leather jacket with peep-toe pumps and slacks.

We love the flowing colors and patterns on Bridget Moynahan's dress, but the wide black accent around the neckline is too strong.

Halle Berry just looks desperate for attention.

Kelly Rutherford's flirty red dress and matching lipstick are cute, but the black tights and pumps weigh the look down.

We love the white, black and powder blue color combo Naomi Watts is sporting here.

Zoe Saldana's timeless leather trousers and dark camel coat demonstrate how a few simple pieces can equate to easy chic.

Jessica Chastain shows off a lovely day look in this ruffled blouse and black satin pencil skirt.
We like the soft look of the loosely tied ponytail.

January Jones — Mad Men is not real life.

Tina Fey steps out of her comfort zone with this edgy leather top and chunky tweed pencil skirt. We like the mix of textures, but proportions are off — the skirt should be knee length, not below.

We feel like we should like Emmy Rossum's Oscar de la Renta dress more than we do. The cut is flattering and the appliquéd and sequined flowers are really lovely. Maybe it's the not-quite-blue-not-quite-gray background color of the dress? And the green satin shoes?

Ginnifer Goodwin's uncomfortable expression says it all. Even she knows this is a fashion misstep.

NeNe Leakes can barely poke her head out of this cumbersome pile of fabric.

This combination of grim makeup and figure-skating style are not working for Olivia Munn.

We don't recall seeing "sexy ringmaster" on the Spring 2013 runways, but Sarah Silverman attempts to convince us otherwise.
