What makes a Fair Isle sweater so special?

Named after a small island off the coast of Scotland, these cozy, colorful, sweaters have been popular since the 1920s, when they were worn by the Duke of Windsor. Made from lambswool and Shetland wool – also named from the Scottish islands – their softness comes from heathered yarns (spun from different colored fibers) that are knitted to form the geometric designs. These patterns are a key look for Ivy-inspired preppy styles, as they’re easily incorporated into a daytime campus-ready ensemble that’s casual without becoming too staid. Wearing these sweaters with an oxford shirt and blazer is also a smart way to add eye-catching interest to your typical ensemble.
