Kate Hudson's Reem Acra gown is pretty, but it's a little too literal when worn to the Tiffany & Co. Blue Book Ball. Also, the design is pretty standard.

With her asymmetrical hairdo and avant garde gown, Michelle Williams takes a page out of Tilda Swinton's fashion book. It works better for Tilda.

Gwyneth certainly has good genes working in her favor. Take a moment to ponder the fact that her mom — the ever-stylish Blythe Danner — is 70!

This bold black and white graphic pattern and asymmetrical hem flatter Erika Christensen's figure.

Hannah Simone is the picture of spring in this watercolor floral. Love the nude-pink polish on the nails and baby blue on the toes.

Carol Brady is that you?! Salma Hayek makes a fashion misstep in this unfortunate '70s- style pantsuit.

Sandra Bullock shows how to do a pantsuit right in this Rouland Moret version. The black nail polish and pointy stilettos edge it up.

At first glance, we were against Jennifer Hudson's mismatched prints and choice of shorts (!) for the red carpet. But, you know, iit's kind of cute vintage pin-up, no?

Love or hate her, Gwyneth Paltrow does have a flare for fashion. The color, length and cut of this Victoria Beckham dress all suit her well. The neon cuff on the sandal is on-trend for spring.

This buttery yellow shade is really pretty on Jada Pinkett Smith, and we like these snazzy black and gold sandals. We would have preferred a nude or rose lip color, but that's getting nitpicky.

Emmy Rossum's gold-fringed Naeem Khan dress is a total knockout, as are her hair, makeup and shoes. Home run.

Jessica Stroup's look has a Little House on the Prairie vibe that's not really working for us.

This may well be the least attractive pattern on a skirt that we've ever seen. It manages to make tiny Julianne Hough look both bottom-heavy and dirty. And yellow satin shoes?!

There's something so "trying to look sexy at the middle school dance" about Mischa Barton's dress. And hair. And shoes.

We love Lily Collins's sheer Valentino shirt, and it's perfectly paired with a leather jacket and pants. Check out the white heel on the stilettos.

Using all three primary colors together in one look would never be our first impulse, but Diane Kruger makes it work. Perhaps the fact that the sandals lean towards a more neon yellow is what makes it feasible.

Eva Mendes goes for a mother-of-the-bride look in this peach ensemble.
