Fashion people were all jazzed that Rodarte created costumes for Black Swan. Of course nothing could be more exciting than bird-inspired Rodarte tutus on the big screen, and of course nothing could be more exciting than Natalie Portman flapping about in them. As the Rodarte Swan titillation fluttered on in the press, someone read the credits and pointed out that designers Kate and Laura Mulleavy are not billed as the film's costume designers, which would cheat them out of an Oscar nomination should the film's clothing earn one. Though the film didn't get the nod, its costume designer, Amy Westcott, asserts that the sisters wouldn't have been cheated out of anything.
