We saw the herringbone texture on a completely different sweater in Shanghai, and we liked the way it gave new life to the conventional solid color. Hmmm, Let's put those herringbones on a sleek zip-front cardigan, add a mock-turtle collar with a contrasting interior to keep things interesting, and then make the first sample in just my size.� This men's cashmere sweater is supremely comfortable. The interior of this double-knit sweater is soft and smooth, like superfine pile. Medium weight. Regular fit.
