The J.Press Shaggy Dog sweater is a classic. Lightweight, warm and scratch-free, it's the brainchild of Irving Press—son of the brand's founder—who first thought of combing the wool to give the Shetland sweater its unique texture. Decades later, the sweaters are still in style, now more than ever. In fact, a few contemporary labels are putting their spin on this iconic piece, tweaking the traditional form and modernizing the fit. From Michael Bastian's stripes to Rugby's shawl collar (with leather elbow patches and a chest pocket), you could definitely say this old dog's learned a few new tricks this fall.
