Ralph Lauren Purple Label Slim-Fit Merino Wool and Cashmere-Blend Piqué Half-Zip Sweater

'Versatile' is an overused adjective in fashion, but Ralph Lauren Purple Label's sweater is the true definition of the term. It's made from a soft merino wool and cashmere-blend and designed in a tidy slim shape. The knitted piqué stitch gives it more of a relaxed feel, though it still looks smart when zipped up and layered under a blazer.
