Although Natalie Portman studied ballet as a child, she "had always hoped to do a dance film. It's the most emotional form of expression," the actress dished to USA Today. Now she's the star of the upcoming ballet slash psychological thriller Black Swan, due out this fall. And although she's been involved with the project for nearly a decade with director Darren Aronofsky, she only brought in her favorite designers, the Mulleavy sisters behind Rodarte, to design the ballet costumes more recently. Portman plays Nina, a ballerina chosen is the lead in a N.Y.C production of Swan Lake. Also starring in the flick is Mila Kunis, who plays a rival dancer. We're loving the dark yet glam choices Rodarte made for Portman's stage costume. Check out more photos from the film in the gallery, and then tell us what you think in the comments section below.
