Lily Collins: Vanity Fair Oscar Party!

Lily Collins turns into the belle of the ball as she arrives at the 2012 Vanity Fair Oscar Party hosted by Graydon Carter held at Sunset Tower on Sunday night (February 26) in West Hollywood, Calif.

The 22-year-old actress floated around in a Monique Lhuiller nude and blue embroidered tulle � sleeve ball gown from the Pre-Fall 2012 collection and Tiffany jewelry.

Just the night before, Lily stepped out at the Chanel and Charles Finch Pre-Oscar Dinner held at Madeo Restaurant in Los Angeles.

There, she wore a ruffled skirt with a cute black jacket from the Chanel Spring/Summer 2012 Ready-to-Wear collection.
