WORST: Jayma Mays channeled Evan Rachel Wood in beaded flapper-esque gown.

WORST: Little Fockers star Kat Kramer was clearly going for a Mad Men look, but looked more tacky than tasteful by adding a children’s clutch.

BEST: Mad Men beauty Elisabeth Moss rocked an emerald-hued Donna Karan sik gown with Lorraine Schwartz jewels and a Judith Leiber clutch.

WORST: We were truly on the fence about January Jones shockingly sexy Versace gown, which featured a cutout bodice. Though it defined red hot, it was a little too boobilicious for the show.

BEST: Sofia Vergara showed off her covetable curves in a red hot Prabal Gurung gown, which was sashed in black.

WORST: Julianne Moore’s one-sleeved magenta gown wrinkled up in all the wrong places. The Kid may be Alright, but this red carpet look isn’t!

BEST: Megan Fox looked pretty (and sexy) in a pink Armani Prive stunner.

WORST: Just because Christina Aguilera was in the movie Burlesque, it doesn’t mean she had to borrow a gown from the set. We kid, we kid. Her embroidered and beaded Zuhair Murad strapless gown, paired with Lorraine Schwartz jewels and Christian Louboutin heels failed to achieve her a best dressed nod.

WACKY: Leave it to Heidi Klum and Seal to up the wacky factor on the red carpet! While Seal wore a liquid black suit with oxford shoes, his Project Runway wife wore an impossible to miss, patterned mess of a Marc Jacobs dress.

WORST: Michelle Williams went for a vintage look with her daisy embroidered Valentino gown, which wasn’t awful, but not amazing either.

BEST: Tilda Swinton really worked this Jill Sander ensemble, which wasn’t red carpet typical, but definitely suited her personality.
