Mainbocher, the first American designer to live and work in Paris, was also influential, with his plain yet supremely elegant designs, often employing the bias cut pioneered by Vionnet. The luxury goods manufacturer Hermès began to sell handmade printed silk square scarves in the early 1930s, in addition to popularizing the zipper and many other practical innovations. Toward the end of the decade, women's fashions took on a somewhat more imposing and broad-shouldered silhouette, possibly influenced by Elsa Schiaparelli. Men's fashions continued the informal, practical trend that had dominated since the end of the First World War.
