Mary-Kate and Ashley Olsen are women of very few words. Ask them about the direction of their new Spring collection, and you get the shortest of briefs: “Raw silks.” That’s not much to go on, but no matter. This show, like most of The Row shows that have preceded it, was highly evocative. Monday morning traffic, the elevator you just missed, your buzzing cell phone… In the face of the serenity on their runway, all that stuff fell away. The setting, a raw, fifth-floor warehouse space in Soho, played a big part. Pouring through skylights, the morning sun glinted off the gold basket weave of a loosely tied coat, and shimmered on an organza top that looked as if it might’ve been dipped in tea or sepia-dyed. Angels, you thought.
