An amazing, rare pair of vintage Elsa Schiaparelli sunglasses will be on sale May 2 as part of a vintage jewelry sale timed to the opening of the Metropolitan Museum of Art's opening of Schiaparelli and Prada: Impossible Conversations explores the striking affinities between Elsa Schiaparelli and Miuccia Prada, two Italian designers from different eras. Sunglasses like the ones above were made in 1957 for American Optical bear a resemblance to Prada's Spring 2012 collection which also includes pieces decorated with enamel roses. Schiaparelli and Prada: Impossible Conversations will be on view starting May 10 at the Met in NYC.
