As the label celebrates 20 years, TSE is refocusing its attention on its core business: cashmere. It's about time: The company's revolving roster of designers—from Narciso Rodriguez to Tess Giberson—has tended to generate more column inches than the clothes. Fall's team-designed lineup was almost monastic in its minimalism. This was a collection built upon layering: Detachable pieces like shawls and hoods were wrapped over unitards, bodysuits, and jumpers, resulting in an aesthetic that was at once classical and futuristic. While experiments like skirt pants and aprons threatened to spin out of orbit, TSE can bank on the rib knit leggings and double-faced outerwear.
