Scarlett Johansson's dress resembles an apron, and those clunky beige sandals just make it all worse.

Julianne Moore puts forth a good effort in this Jason Wu dress, but we have a few quibbles. It seems a little too formal for a movie premiere and could use a more defined waist.

Claire Danes' Valentino dress actually has a lot of pink detail in the flower appliqués that saves it from going full bridal, and her hair and makeup are flawless.

We like the combo of ballet-pink shoes and black belt with Zooey Deschanel's white dress.

Nicole Kidman makes a suit sexy with these lean cigarette pants and pointy-toed pumps.

Julia Roberts dons a look last seen at the Grand Ole Opry in the '70s.

This wine satin dress is gorgeous with Christina Hendricks' hair and complexion, and the fit is quite flattering. But the big floppy sleeves ruin the silhouette.

This Calvin Klein slip dress really suits Rooney Mara's modern, edgy persona. The gray smokey eye and nude lip are gorgeous on her.

Draw Bella Thorne appears to be going through her teen bohemian phase. Which is fine, but these shoes belong to a different phase.

We love Hailee Steinfeld's cute, blue retro look, complete with matching cardigan and ladylike bag.

Parker Posey has been wearing a lot of this "crazy old lady" look lately. Maybe it's performance art?

We love the gorgeous landscape print on this dress by Mary Katrantzou. The strapless top and full skirt is one of Keira Knightley's favorite silhouettes and is worn to great effect here.
