New York-based label Khaite is noted for its polished reimaginings of classic American sportswear, as demonstrated with this jade-green roll-neck Wallis sweater. Crafted from chunky-knit Mongolian cashmere, it features a distinctive rounded seam, extra-long drop-shoulder sleeves and a slit in the centre of the back hemline. Emphasize the slouchy silhouette by teaming it with relaxed cropped trousers to take you from day to night.
