American designer Anna Sui launched her first collection in New York in 1991 and has remained on the top list of U.S. fashion designers ever since. A Lifetime Achievement Award winner, Sui currently lives in Manhattan and added a third penthouse to her collection of homes in April 2011. She already owned two apartments in the Greenwich Village co-op, a ninth-floor one-bedroom and a separate penthouse into which she expanded in 2008. Sui's apartment interiors, like Ralph Lauren, have been featured in several design magazines and most recently in Elle Decor.
