My jaw dropped when I saw Lily Collins at the 2012 Vanity Fair Oscar Party in West Hollywood last night.

Lily looked picturesque in a Monique Lhuillier Pre-Fall 2012 nude and blue embroidered tulle ¾ sleeve ball gown.

Set to appear as Snow White in this year’s ‘Mirror, Mirror,’ Lily looked every bit the princess in this show-stopping gown.

The star-making dress was accessorized with Tiffany & Co jewelry and a tousled up-do.

Should she have saved this for the ‘Mirror, Mirror’ world premiere?
