Natalie Portman

One of the things we love most about Black Swan is that it gets all the little details right--down to the practice clothes. Nina and Lily's refined leotards are exactly the sort of chic, understated pieces real ballerinas would wear. That's unsurprising, given that dancewear superstar Yumiko designed the leos especially for stars Natalie Portman and Mila Kunis.
