You could spend an hour staring at one of Mary Katrantzou's pieces. Sometimes I almost do, and I know I'm not the only one. Like a magic eye puzzle or an aquarium ceiling, their power is the ability to stop people in their tracks and keep them there, eyes fixed and cool blown. And now that the whole Spring/Summer 2012 collection is spread out on OCNY's racks, there's a lot more ogling to be done. Flowers in CMYK colors, fish with the saturation turned to max, and backgrounds streaked like the underside of a CD; the prints this season are more exquisite than ever.
