Successful relationships are forged by the shared desire to continually bring out the best in each other. That's the essence of Y-3, Yohji Yamamto's union with adidas, now entering its 11th year of creating futuristic sportswear. Never complacent, Y-3 enlisted esteemed graphic director Peter Saville to assist on its Spring/Summer 2014 collection, which is less a mash-up than a seamless blend. "We created something that has never existed in the world, and completely projected in the future," says Yamamoto. Long may Y-3 stay together.
