Wow! We've never seen Kat Graham wear her hair curly, and it looks fabulous! The slit is on the high side — the bold print makes enough of a statement on it's own — but all else is top notch.

While we love Lucy Liu's Roland Mouret gown, we're having a hard time processing the Roberto Cavalli cape.

The idea behind Cameron Diaz's Stella McCartney dress is better than the execution. The minimalist style and palette are appealing, but the top half looks like a bathing suit, and the skirt pooches out in an unflattering manner.

Kourtney and Kim Kardashian wear pieces from their own line at the launch party for the UK Kardashian Kollection for Dorothy Perkins. We like Kourtney's stockings and shoes — which are by Wolford and Alexander McQueen. We're not sure what that says about the Kollection.

Archie Panjabi whips out her sexiest black leather dress for the Victoria's Secret Fashion Show after party. We think this outfit calls for an edgier shoe (a pointier toe, at the least), but she still looks hot.

Rihanna looks rumpled and tired.

Keira Knightley is stunningly elegant in this Valentino gown. Nobody wears the slicked-back side part and red lipstick look as well as she does. The lace overlay is actually midnight blue, a subtle but pretty change from black.

Simple designs usually work best for Christina Hendricks, seen here with this cap-sleeve, below-the-knee dress. The sparkly sequins and peep toes dress it up.

Elle Fanning is totally age appropriate and adorable in this gown, but the cabana stripe and white accessories feel too summery for this time of year.

There's a fine line between being a fashion icon and "that guy that wears weird clothes." Alan Cumming has crossed it.

Natasha Henstridge's gown is flattering and has some nice subtle details. (Note the pretty corseted effect from the horizontal binding at the waist.) But it's just too much red with the matching lipstick and clutch.

Kim Cattrall is looking more Camilla Parker-Bowles than Samantha Jones in this getup. Sam would not approve.

Katrina Bowden is seen here in one of those Herve Leger-style bandage dresses that already felt past their sell-by date a year ago.

Kerry Washington is seen here in a dress by Mary Katrantzou (currently fashion's mixed-print darling). It's a love-or-hate thing — and we are in the love camp. The high ponytail, cat-eye liner and black accessories are just right.

Emily Blunt certainly has the right figure for this sleek column of a dress, and the tangerine color is striking.

The silver beaded pattern on this gown is to die for, but it swamps Gillian Anderson's petite figure.

Aisha Tyler's dress could use a wide black belt to really complete the look, but we love the slashes of red and the New Wave feel.

The neckline of this Stella McCartney dress is a little odd, but this lemony yellow shade really suits Jessica Chastain. The scalloped hemline is a nice detail.

Marion Cotillard's Christian Dior dress has a fabulous high-low tulle skirt, and strapless gown with a diamond choker is always classically elegant. Note the white pumps — it's a trend you'll be seeing more of.

Cheryl Burke's combo of cobalt silk dress and beige pumps just feels so '80s — not in a good way.

Kelly Osbourne looks OK in this Zimmerman dress, but she's about to accept the Ultimate Style Award at the Cosmopolitan Ultimate Women of the Year Awards 2012. Do you think she deserves it?

We find it difficult to avert our eyes from the psychedelic pattern on Olivia Munn's Peter Pilotto dress. If that's the intention, it certainly succeeds! But we would prefer to see this sleeveless and paired with a simple pump.

Paula Abdul's entire look can be encapsulated by one simple phrase: "mutton dressed as lamb."

We have no idea how Nicole Scherzinger managed to find lipstick in the exact neon red-pink shade of her shoes, but we applaud the effort.

Louise Roe is well known in England as a television show host and journalist specializing in fashion. We question her expertise due to this appearance with a cartoonish clutch and frizzy hair.
