Oscars 2013: Costume design nominees

Keira Knightley on the set of "Anna Karenina." Costume design by Jacqueline Durran.

"Anna's thematic scheme of color is dark -- particularly with the red she wears at the beginning, in the Karenin home," Durran said. "What she wears becomes somewhat lighter in tone when she becomes enraptured with Vronsky, before returning to the darker hues as she becomes anxious and paranoid that his affections towards her have waned."
