Rei Kawakubo’s fascinating, reality-defying designs for Comme des Garçons are captivating on the runway, and will surely draw crowds to the Costume Institute next month. But if you’re the one wearing the three-armed jacket, pencil in extra time for sidewalk interrogations. “You have to really plan ahead how you’re going to get from point A to point B, and be ready for confrontations and conversations and people interacting” with what you’re wearing, says Michelle Elie, the designer and street-style star who regularly wears Kawakubo’s most outré designs. Elie once got into a taxi wearing one of the sanguine pieces from the Blood and Roses collection. Her cabdriver told her, “I don’t understand what you’re wearing, but I do have to say you look exceptionally outstanding, and keep it up.” When she tried to fashion-splain Comme des Garçons to him, “he didn’t know much about it, but he did say it was the best thing he’d seen all day!” she recalls.
