Olivia Wilde is Vanity Fair Fabulous

Olivia Wilde is radiant in an RM by Roland Mouret “Hydra” dress on the red carpet at the 2010 Vanity Fair Oscar Party hosted by editor Graydon Carter at the Sunset Tower on Sunday (March 7) in West Hollywood, Calif.

Before the 2010 Oscars, the 25-year-old actress presented at the Independent Spirit Awards with John Waters – Eddie Izzard served as the host!

“If he wears the same dress as me, i SWEAR TO GOD…” Olivia jokingly tweeted before the show.

FYI: Olivia sported red satin Ferragamo peep toe shoes with high heel and double platform and carried a Judith Leiber clutch!
