Black and white is a timeless combination, but it gets new energy this fall from creative interpretations. Mike Amiri went casual with a printed sweatsuit, enlivened with scribbly ink drawings and checkerboards. The Row, ever sophisticated, used a deep brown and cream (rather than true black and white) for a graphic coat that ties at the waist. Beijing-born Snow Xue Gao softened the effect of a black-and-white plaid skirt by pairing it with a snug, floral-printed top. Ashlyn Park, a former patternmaker for Yohji Yamamoto, used her zero-waste philosophy for a fabric-blocked blazer. And Tanya Taylor brought an artistic yet romantic mood to the pen-and-ink palette with silhouetted black blossoms.
