With his signature jacquard and velvet fabrications, designer Erdem Moralioglu is the king of ornate eveningwear. But how does he keep it contemporary? With his footwear, of course. At London’s National Portrait Gallery today, he introduced brogues and styled them with ballgowns. This season’s muse was Adele Astaire, Fred Astaire’s showgirl sister who, according to the designer, was infinitely more talented. The American dancer married the British son of the Duke of Devonshire.
