As we look back at The Year in Fashion, 2015 is a year of goodbyes and retrospectives, but also a time to look ahead. Jean Paul Gaultier bids adieu to ready-to wear. Peter Copping debuts his first collection for Oscar de la Renta. With the exhibition China: Through the Looking Glass, the Metropolitan Museum of Art stages its biggest costume extravaganza yet. Donna Karan takes her last bite of the Big Apple. Fashion meets art with the retrospective exhibition Ralph Pucci: The Art of the Mannequin. We put the spotlight on model extraordinaire Cara Delevingne. The 2015 CFDA Awards celebrate the year’s best. Plus runway shows from Carolina Herrera, Alexander McQueen, Julien MacDonald, Emilio Pucci, Burberry Prorsum, and the opening of the new Whitney Museum of American Art in New York City.
