Amy Poehler looks like she mowed the lawn and glued the grass onto her dress — not quite red carpet style.

We like the idea of Mia Wasikowska's dress, but the length hits at an unflattering spot and the shoulders look too big for her tiny frame.

Nikki Reed has the right amount of color paired with her sheer black tights. The belt pulls together the look, we just wish she had pulled together her hair.

Leopard prints aren't easy to pull off, but this dress has just the right amount of sass. The natural makeup and pulled-back hair works well with the loud dress.

It may be winter, but Gillian Anderson could have removed her coat before hitting the red carpet. The all-black look doesn't do much for her pale skin and blonde hair.

Tia Carrere has the right idea with her long-sleeved navy dress. The keyhole cutout in the cleavage takes away from the simplicity of the look.

Bradley Cooper is rocking his tailored suit with just enough color in the shirt peeking out to give it some style.

We're not sure what year — or decade? — Heather McComb thinks she's in, but the headband around her forehead paired with the lacy off-the-shoulder top does not say 2011.

Is Virginia Madsen moonlighting as an extra in a Pepto commercial? Other than the hideous color, the bow and bubble skirt don't help pull this look together.

Abbie Cornish is going for boy-chic, but fails. The suspenders over the white silk top isn't flattering, nor is the tailoring of the pants.

Jena Malone looks miserable in her all-white outfit, which includes a frilly dress with matching blazer.

Jennifer Lopez is bringing back plaid, but not in a good way. The shirt is too short and reminiscent of Britney's "Baby One More Time" video.

Michelle Trachtenberg is high fashion in her slate gray dress with bunched fabric creating the one shoulder. With so much detail on the dress, the actress played it smart by having a sleek ponytail.

Deborah Gibson thinks she's still in the '80s, where all of her hit songs live. At least her look fits right in with the period film's premiere

Anna Faris looks great in red, but the shoes are too matchy-matchy.

Kimberly Elise is shining in silver. The dress is tight in the right places and her jewels and handbag match perfectly.
