Marion Cotillard knocks it out of the park in this vintage-y glam Christian Dior couture dress. Using that intense orange-red as an accent color for both her lip and shoes is particularly au courant.

The shapeless drape and dried-flower collar of Anne Hathaway's gown remind us of a Mother Nature costume.

We don't require couples to dress in entirely matching outfits, but both the color and style of Alexandra Edenborough's and Gary Oldman's garb appear to be entirely out of sync with one another. Is this mirrored by their body language?

We're tempted to chalk this one up to teen fashion overexuberance and give her a pass, but Hailee Steinfeld may be regretting this polyester-looking dress and awkward wooden platforms when she sees the photos.

We're not sure which frightens us more: Michelle Trachtenberg's bride-of-dracula makeup or the peach satin pumps.

Anna Gunn works a blonde bombshell look in this sequined pencil skirt and retro pointy pumps.

Lea Michele's floral lace dress is cute and it's a flattering shade of blue, but we're most enchanted by her shiny golden-brown hair and natural makeup.

Heidi Klum's choice of gray shoes and accessories (rather than the more usual black or metallics) looks fresh with a black dress.

We get Noomi Rapace's androgynous/menswear look, but this interpretation is a bit too literal (excluding the pumps, of course). It would benefit from more feminine tailoring.

With the orange tan, tacky bustier dress, purple strands of hair and striped stripper shoes, all Ashley Tisdale needs is a husband to land on one of the Real Housewives franchises.

Michelle Williams goes for a Comic-Con-friendly look with this vaguely sci-fi graphic print dress by Giulietta. It's cute, but the shoes have a formal feel that just don't mesh with this casual dress.

We will never approve the pajamas-as-day-wear look. Go back to bed Elizabeth Reaser!

Zooey Deschanel continues to reside on Planet Twee. Can we please ditch the hairbands and cartoon-ish accessories?

Hayden Panettiere is the quintessential California babe — all blonde hair, golden tan and dressed in the colors of ocean and sand.

Statuesque Maria Sharapova radiates "greek goddess" in this cornflower blue fortuny pleated gown.

Here's Connie Britton on her way to the grocery store. Oh, wait, no she's not.

Everything about Cheryl Burke's look just feels off, from the fishtail braid to the drab brown color palette.

Yes, redheads often look terrific in shades of green. And Alicia Witt's bangs and blunt cut are super cute. But she needs to pick either the shiny top or the orange sash — not both.

One day, people will look back back at bat wing dresses like Ricki Lake's and realize that they are the '70s caftans of the 2000s.

Missi Pyle's white dress is fairly basic, but we like the way she accessorized with a silver metallic belt and grey shoes. Same color family but a difference in intensity and texture.

This Marchesa dress makes Katy Perry look thick through the middle and the poofy skirt is just tacky.

Elizabeth Banks looks fantastic in this dove grey Versace. Normally, we would say the shoes are too matchy-matchy, but they work here. The metallic silver clutch is exactly right.

Christina Hendricks' unflattering jacket looks as though it was borrowed from an entirely different outfit.

This studded leather Versace dress harkens back to Jessica Alba's tough-girl Dark Angel days.

Marion Cotillard takes this sweet floral babydoll dress in a sexy direction with those sky-high strappy wedges.

Diane Kruger's look just screams Carrie Bradshaw-goes-to-Paris.

Only a native Frenchwoman like Clemence Poesy can pair messy hair and men's brogues with a sparkly Chanel couture dress and get away with it.

We like the summery and slightly '70s style of Kirsten Dunst's pink Louis Vuitton maxi dress.

We give a thumbs up to Tiffany Hines' accessories, from the the white metallic clutch to the textured blue pumps. But that dress looks like an ice skating costume.

We understand and appreciate Sofia Coppola's flair for chic, minimalist style, but sometimes it just starts to look a little dreary.
