In a collection that was about as different as night and day, Raf Simons channeled the viewpoint of photographer Diane Arbus for fall, elevating early-sixties fashion with Pop Art color. The results were a mesmerizing mix of interesting combinations: tulip tops with ski pants, stiff quilted wools held in place with padded satin layering and plenty of ski sweaters in riveting colors. If there was a whiff to Balenciaga, it came in the shaped chemise dresses and coats cast in the breathtaking floral prints that begged the question: is it a dress? A coat? Both?
