Let The Devil Wears Prada references begin. Tonight Anna Wintour will be greeting her guests atop The Metropolitan Museum of Art’s iconic steps in a custom Prada gown. “I’m wearing Prada’s homage to Elsa Schiaparelli” the editrix said. It’s a fitting choice for the editrix as this evening’s festivities, which raised over $11 million for The Costume Institute, are in celebration of the museum’s latest exhibition, Schiaparelli and Prada: Impossible Conversations. “They both believe in breaking the rules of fashion, which is something I believe in too,” said Wintour of the two female design talents.
