Yasutoshi Ezumi, who cut his teeth at Alexander McQueen and Aquascutum before launching his own brand a few years ago, has earned a reputation for his knitwear. This season was no different, as he turned out knit dresses, sweaters and garments constructed of draped fabric in a palette of black, gray and neutral hues. Entitled “Natural Selection,” the collection also featured a honeycomb, botanical pattern.
