Heidi Klum works a '70s era Cheryl Tiegs vibe, showing off her long, tanned limbs in these ocean blue colors, complete with matching eye shadow.

The combination of ivory and white is pretty, but Jennifer Lopez loses us after that. Why the addition of that tiny, tight belt? And that lacy bodice is matronly.

Cate Blanchett looks her usual chic self in this Alexander McQueen ensemble, which is accented by a red lip and sideswept bangs.

Kaley Cuoco's matching shorts set is just a no.

Famke Janssen's dress looks more like it's wearing her — she appears to be trapped inside this boxlike gown.

We love the unexpected tweedy texture of this pink, strapless dress. Naya Rivera looks great in this color, and the silver sandals add extra flair.

Karen Gillan shaved her abundant red locks for a film role and accentuates her new style with this edgy-but-cute androgynous look.

This shapeless dress does no favors for the petite Ginnifer Goodwin.

Mary-Louise Parker shows off her gams in this ethereal gray and silver chiffon dress. A black-accented white clutch and silver Jimmy Choos complete the look.

This dress belongs in an '80s nightclub, not on Kat Graham.

Angie Harmon's leather dress is pretty great, but we'd change the shirt tail hem to a straight one and tidy up that hair.

Did Scarlett Johansson's bags get lost at the airport? We can't come up with another reason to explain these black pumps with this sunny summer dress.

We're sure it's not, but Catherine Zeta-Jones' hi-lo lace dress looks cheap.

Helen Mirren's emerald Elie Saab gown could not be more figure-flattering. Coral accessories are a surprising color accent that really works.

Bruce Willis works a Gatsby look in this white linen suit, complete with pocket square and burnished brown oxfords.

Maybe it's our sheer-overlay fatigue or this shade of green, but Diane Kruger's dress just leaves us cold.

The uneven hem and odd piece of fabric between the straps are ill-advised attempts to "jazz up" Olivia Munn's simple black slip dress.

Blake Lively's skirt is encrusted with what appear to be those glass stones used for floral arrangements.

Emmy Rossum's Carolina Herrera gown is an almost. We love the lush floral pattern on the skirt and the overall color scheme, but the design of the top half seems a little awkward. Are we too picky?

Kate Hudson's gown shoots for "dramatic" but ends up at "shapeless." Her hair and makeup are stunning, however.

Tadashi Shoji designs yet another lovely dress for his celebrity muse, Octavia Spencer.

Sandra Bullock goes glam beach babe in this Emilio Pucci dress paired with sky-high Roberto Cavalli sandals.

Jennifer Lawrence is wearing a cropped top and pants (?) from the Christian Dior Resort Collection, and it's not really working. The proportions are odd and the aviators, while an ever-trendy fashion accessory, just don't look right here.

Kristen Stewart takes this conservative Chanel jacket to an edgier place by pairing it with black cut-off shorts, fingerless leather gloves and killer shoes.

We can't help but feel that Naomie Harris left a button undone in this otherwise unnoteworthy outfit.

It's really time for Nicky Hilton to update her look — she's been wearing similar outfits for a decade.

Nothing in Milla Jovovich's ensemble seems to work together — the shirt is too casual, the bag too dressy, and the skirt is just frumpy.

Leelee Sobieski's Christian Dior look is a variation of Jennifer Lawrence's outfit, but the solid color and lack of exposed torso create a more flattering look.

Sarah Jessica Parker's silver-fringed Naeem Khan is just gorgeous and shows off her legs and shoulders to great advantage. She could stand to lighten up on the eyeliner, however.

This may not be for everyone, but we love the androgynous quality of Clemence Posey's bow-tied Chanel jacket and skirt.

Uma Thurman looks great in this simple but sexy black dress (note the cutout details down the sleeves), and the wavy, undone hairdo is fantastic.
