Talley says that man’s sartorial equivalent of the LBD is a navy-blue suit. But that didn’t stop the curator from including a gender-bending dress in the exhibition. Among the ladies’ gowns is a lace “male shirtdress” designed by Comme des Garçons—the same one Marc Jacobs wore to the Met Gala earlier this year. Jacobs completed his look with white boxer shorts and sparkly pilgrim-style shoes, and the bro-frock sold out soon after.
