The presentation of Yoshiyuki Miyamae's second women's collection for Issey Miyake was a reminder of the subtle but impressive ingenuity of Japanese showmanship. The show opened with a practical demonstration of "steam stretch," a new fabric technology that uses applications of steam to shape clothes woven from a combination of silk and stretch yarn. Within seconds, anonymous squares of fabric were completely transformed into sinuous dresses. It was a spectacular effect, subsequently compounded by a show that featured more of the same. There was never a dull moment, because there'd be another innovative something or other along within seconds.
