Miley Cyrus in Roberto Cavalli | 2012 Vanity Fair Oscar Party

Miley Cyrus was a party animal on Sunday night! Not only did she watch the Oscars with Elton John at his annual viewing party for his Elton John AIDS Foundation but she, and her boyfriend, Liam Hemsworth also hung out at the Vanity Fair party.

The 19-year-old performer looked better than ever in her open back dove grey long-sleeve gown by Roberto Cavalli with a glorious silk waterfall asymmetric mermaid train.

I love the metallic palette trimmed embellishments and the open back design that featuring little buttons starting at her rear and going down the rest of the dress.

Everything about this dress was so intricate and beautiful — and Miley accessorized like a pro! She finished off her look by styling her short ‘do in retro curls, lathering her pout in siren red and donning her ears in bold diamond Lorraine Schwartz earrings that matched her pearl cocktail ring.

She completed her look with crystal embellished dark silver “Falcon” sandals by Jimmy Choo, and of course, Liam.

The dashing star of “The Hunger Games” wore a nice Calvin Klein Collection suit.
