Miley Cyrus, Leighton Meester Among Movie Awards' Best-Dressed Females

Sienna Miller, Malin Akerman, Ashley Greene also make the list.

What's better than winning a tub of Golden Popcorn at the Movie Awards? Getting our vote for best looks of the night, of course. So put on your fashion thinking caps and check out which actresses' closets we're just dying to raid.

Malin Akerman: The actress must've taken cues from her "Watchmen" alter ego, Laurie, because, man, was she kicking major butt on the red carpet! Dazzling in a crisp, white, fitted Dolce & Gabbana suit, a super-sleek updo and a metallic gray corset, Akerman looked like the sophisticated starlet we always knew she was. Plus, she knows how to accessorize without overdoing it: That major blue rock on her right hand added the perfect pop of color. Let's just hope she's carrying some stain remover with her, you know, just in case any of those crazy attendees (paging Will Ferrell!) spill anything on her immaculate outfit. That would be tragic.

Miley Cyrus: The teen queen has often fluctuated between styles, with some of her past red-carpet looks either bordering on too sophisticated or too young. At the Movie Awards, in an understated nude Moschino dress paired with cream-colored heels, the "Hannah Montana" star found the best of both worlds. The form-fitting silhouette, cowl-neck halter and fresh makeup added a dash of class, making her look streamlined. Her chunky silver accessories and turquoise nail polish, however, were totally fun and age-appropriate. Same can be said for the origami-trimmed back, which added some flair.

Ashley Greene: Old Hollywood glamour sashayed onto the scene when this "Twilight" star made her entrance. Much like her fellow best-look cohort Malin Akerman, Greene also seemed to channel her big-screen identity Alice Cullen with a style that was so put together, it was practically supernatural. OK, maybe we're going a little far, but in her floral-print sheath, paired with purple platforms and a neon clutch, the actress looked like she came straight out of the 1940s. Special shout-out to her hair and makeup people for giving her adorable pin-curled hair and perfectly pouty red lips.

Sienna Miller: OK, so she arrived with some pretty smokin' arm candy (ahem, her "G.I. Joe" co-star Channing Tatum), but Miller was also looking smokin' herself in a sexy, backless, emerald-green dress. She's obviously tuned into fashion because the Swarovski-encrusted frock was from — wait for it — her own label, Twenty8Twelve. When she has graced red carpets in the past, the bohemian actress has often preferred a simple, carefree style. But she managed to bring flirty elegance to the awards show and made it look effortless. If only it was that easy for the rest of us.

Leighton Meester: Quick, someone alert "Gossip Girl"! Blair Waldorf has been replaced by a look-alike in a dress Blair would — gasp! — never dare wear. In all seriousness, we loved seeing Meester shed her token headbands and über-preppy uniform to show off her more mature, provocative side. Her sheer Emilio de la Morena dress, Brian Atwood purple suede booties and silver cuff were complemented by an updo and sultry, smoky eyes. If Chuck Bass could see her now!
