2012 Oscars: What All the Stars Wore
Sunday's Academy Awards marked the biggest night of the year in Hollywood -- and both newcomers and veterans pulled out all the stops for their evening wear when they arrived at the Hollywood & Highland Center in Hollywood.
But two red carpet rookies in particular stood out: Jessica Chastain and Rooney Mara.
Chastain, who received a nod for Best Supporting Actress for her role in The Help, sparkled in a black and gold Alexander McQueen gown teamed with a whopping $2 million worth of Harry Winston jewels.
Meanwhile Mara, who starred in The Girl with the Dragon Tattoo, surprised everyone when she ditched her usual black attire and stepped out in a white, fashion-forward Givenchy number.
