Shocking! The Art and Fashion of Elsa Schiaparelli was an exhibition at the Philadelphia Museum of Art back in 2004. However, the museum's website still hosts a great online resource celebrating the work of the surrealist couturier. Most fun is the Kids Zone, where you can play in a dressing room full of Schiaparelli clothes and accessories.
