A grand apartment at 320 Central Park West has sold for $4.95 million to Kaspar and Kimberly Sykes.

The seller was Jean-Pierre Radley and his wife, Jane Tucker.

Radley is the son of Pauline Trigère, the “grande dame of American fashion.” He began working for his mother’s fashion house, Trigère, Inc, in 1960 and ran the company for its last 15 years — until its demise in the 1990s.

Born in Paris, Trigere fled to New York, during Adolf Hitler’s rise to power, with her husband Lazar Radley.

Corcoran’s Steven Cohen and Jerry Huang were the listing brokers.
