Emma Stone Wears Elie Saab To The Oscars

Stone, who was nominated for Best Supporting Actress for her work in Birdman, looked regal on the red carpet, wearing a golden chartreuse Elie Saab gown. The custom made dress, complete with beaded detailing, featured long sleeves and a sexy open back. Stone paired the gown with Christian Louboutin shoes and Tiffany & Co. diamond cuffs and earrings, making an impressive entrance on the red carpet.

The gown also featured a thigh-high slit, and showed off a bit more skin than Stone intended. While adjusting the skirt of her gown on the red carpet, Stone accidentally gave photographers a peek at her nude underwear.
