Tribeca Film Festival
Grade: C-

Unfortunately, the cutouts on Alexis Bledel's dress had the exact opposite effect. Instead of flattering her frame, they made her look ill-proportioned.

"Star Trek's" Zoe Saldana looked out of this world in her red Emilio Pucci creation.

Simon Pegg's modern take on a traditional kilt had us running for the hills ... or in this case, the highlands.

"Ghosts of Girlfriends Past" Los Angeles premiere
Grade: D-

Normally, Bai Ling's gets an automatic fail. However, the fact that she managed to color coordinate and miraculously stay covered up earned her a few extra credit points.

"Ghosts of Girlfriends Past" Los Angeles premiere
Grade: B

"Party of Five's" Lacey Chabert is definitely all grown up. Her teal goddess gown was gorgeous, but needed an accessory (a belt perhaps) to pull it all together.

Evan Rachel Wood looked nice but predictable in her strapless black dress. And in our book, predictable equals average.

Not only was Kristen Stewart's Herve Leger by Max Azria dress visually interesting, its pattern gave the svelte starlet the illusion of curves.

Viola Davis looked terrific in white, but this embroidered Tory Burch sheath was a bit too matronly.

Grade: D

The super petite Mary-Kate Olsen often gives the impression that she's swimming in her clothes. Here she looked like she just stepped out of a pool.

Many antique lampshades gave their lives to create Patricia Clarkson's fringed fashion faux pas.
