It was all about the materials at Sies Marjan on Sunday, the most significant European designer showing in New York this season. Novel and artisanal fabrics were worn by a cast that walked around the 54th floor of the brand new One Manhattan West building, a curvy skyscraper built two blocks west of Penn Station. Yet the blend of revolutionary fabric techniques, eye-popping biodynamic dyes and truly novel silhouettes meant the audience kept their focus on the collection and not on the view – a truly beautiful late afternoon vision of quite literally the majority of the island of Manhattan under a moody winter sky.
