Inspired by a classic marinière, this sweater is knit from a substantial seven-ply wool-cashmere yarn, which is warmer (and less likely to pill) than the more commonly used, lower-ply yarns. It has a relaxed fit with dropped shoulder seams and a hem that hits at the low hip. Chunky ribbing dials up the cozy factor. In cheery butter-on-baby-blue stripes, it’s the kind of piece that’ll make you happy whenever you wear it.
