An Issey Miyake show is an education, but in the gentlest way. The pitch is usually intimidatingly academic; the execution is always enthrallingly intimate. Today, the foundation of the collection was taping, so basic to the manufacture of clothes, but here transformed on the runway before our eyes into an exercise in pure form. In a matter of seconds, black-clad assistants folded and stapled paper tape, origamilike, into five items of clothing: a tailcoat, a dress, a skirt, a peplum jacket, a collar. Models wearing these paper garments were followed by other girls wearing fabric versions of the same look. It was an inventive insight into the process of design. But that is typical of Miyake designer Dai Fujiwara. This was his last collection after five years as creative director. In a week where good-byes have been very much on fashion's mind, his was one that you wished more people had taken the opportunity to experience.
