Thought the Metropolitan Museum of Art has yet to confirm, rumors have been swirling that Rei Kawakubo will be the subject of the Costume Institute’s spring exhibition. If there is truth to the gossip, Kawakubo will be the second living designer to be honored with a show at the venerable institution. The last was Yves Saint Laurent, who was the subject of a 1983 show organized by Diana Vreeland. Kawakubo founded Comme des Garçons in 1973 and is celebrated for her austere, cerebral designs.
