Always classy, never trashy, Reese Witherspoon is the epitome of old-Hollywood fashion sense. This strapless sheath dress from the Armani Privé Spring 2015 collection would bring out Witherspoon's blue eyes, while the embroidery would add extra glamour to the film world's biggest celebration. Witherspoon is nominated for Actress in a Leading Role for memoir-turned-movie Wild.

Jones is nominated for Actress in a Leading Role for her performance as Stephen Hawking's wife in The Theory of Everything.
