Cindy Crawford puts on the supermodel show in this glam Roberto Cavalli gown, accessorized with a (huge) diamond bracelet and earrings.

Evan Rachel Wood scores originality points with this shirt dress by Alessandra Rich. Everything works, from the slicked-back hair to the mesh skinny-strap stilettos.

Kate Winslet's dress looks like it was crafted from brown packing tape and neither the color nor the fit are doing her any favors. The overall impression is one of bulkiness, and she is not a bulky lady. Her poor shoe choice is compounding the situation.

Keri Hilson rocks this graphic look. Attention to detail is noted in the way the black ankle strap on her sandals echoes the red band on the dress.

While the top half of Zoe Saldana's dress is gorgeous, it looks like she accidentally ripped off the bottom half getting out of the limo.

Anne Hathaway's Alexander McQueen dress resembles a giant doily. And those shoes seem to be entirely out of left field.

Although we're generally against that whole dress with pockets thing, it seems to work better with the more casual "day dress" Kate Walsh is wearing here. The color, cap sleeves and just-above-the-knee length are all very flattering.

Helen Mirren — so close! The scarlet dress, cute bob and red lipstick — all fabulous. But it all fell apart below the knees. Hose with a more matte finish and simple black pumps would remedy the situation.

We have a feeling this opinion will create controversy, but somehow this busily-patterned dress (worn with sparkly silver pumps, no less) actually looks right on Kelly Osbourne. Don't try this at home.

Pauley Perrette is simply wearing the leopard-print version of the black slip dress she's often spotted in on the red carpet. But even this small change adds a little interest to a look that she has made her signature.

Kim Kardashian's sleek white gown hugs her curves in all the right places. We particularly love the middle part and the ponytail.

This strapless black and white Alexander McQueen dress is one of the most flattering dresses we've seen Jane Lynch wear.

Demi Lovato was beaming on the blue carpet in her flirty, vintage-inspired halter dress. The drop earrings play nicely off the silver beading.

Sophia Bush goes for the goddess look in this softly flowing Tibi dress and dramatic Iosselliani necklace.

Listen, we know you guys seem to be against the color block thing (we've seen your previous comments) but we love this look on Rashida Jones.

On the other hand, we are not loving that look so much on Tyra Banks. These colors are just not complementary and the whole look is a little too casual for an event where everyone else seemed rather dressed up.

Zoe Kravitz, Jason Momoa, and Lisa Bonet certainly make for one stylish — and attractive — family.

Rose McGowan's Blumarine ombre dress is a stunner. Her long, wavy locks and the sparkling tones of green and blue lend a mermaid effect without being overly costumey.

1980s-inspired gaucho is probably not the look Rosario Dawson was hoping to embody.

We're so used to seeing Cat Deeley with big hair and a spangly dress that we didn't recognize her at first. The white dress and pulled-back hair give her that "cool blonde" look made popular by several film noir screen sirens.

We like Jennifer Love Hewitt's '70s inspired hairdo. She just needs to shorten the hem of this dress and inch or two and belt it.

Yes, Sarah Silverman is a comedian, but must she always dress like a clown on the red carpet?

Lea Michele just looks kind of so-so here. This rather plain black halter dress is more suited to someone older in years. She she should wait to wear something like this until she has to.

We realize Diane Kruger was likely going for something Dietrich in effect, but all we keep thinking of is Eddie Munster.

Claire Danes' silk wrap dress, gold cuff and loose updo are all classic elements of summer chic.

We hear that Morena Baccarin is growing her hair out — we wish she wouldn't! This sassy little dress is the perfect accompaniment to her gamine hairdo.

Rachel Bilson is seen here in bright red Erdem pants and a floral blouse. And leopard pumps.

This robe-like dress makes Kat Dennings look like she is waiting her turn for a blowout at the local salon. We think her striking looks could be better served.

Kristen Bell is fetching in this black strapless Versus dress. The sparkly silver clutch and round-toed satin pumps complete the look.

Marilu Henner looks terrific for her age. But is this dress age-appropriate?

Jamie King's sheer lace Valentino dress is cute, and the cut of the neckline and sleeves is really flattering. We'd like it better with less frumpy shoes.

Neither the blue pattern nor the toga party styling of this dress are very flattering on Mary Lynn Rajskub. The clunky beige platforms just make it all worse.

AnnaLynne McCord is wearing an outfit more suited for playing in the local softball league than attending an event sponsored by the people who sign her paychecks.

This bold floral print and long, sleek ponytail accentuate Natasha McElhone's tall frame.

We've just seen the short, tight, shiny nude dress way too many times on the red carpet in recent months. We know that Poppy Montgomery has been working out hard for her new role in Unforgettable, but there are other ways to show it off.

Robin Tunney's bright smile can't win us over — her rick-rack patterned dress and ungainly shoes are just not working.

Emmy Rossum wears an Etro dress displaying one of this summer's most popular trends: bold, graphic color combinations. The sleek sandal in a matching tone is the perfect footwear choice.
