Fair isle is a pattern used often around this time of the year. Usually on your favorite Christmas sweater or a cozy blanket laying around. Its rare that you'll see fair isle on..the sleeves of a shirt? This fair isle knit shirt by Comme des Garcons HOMME x gim defies the laws of style, with fair isle knitting along the shoulder, sleeves, and rear panel; not to mention the elbow patches for a traditional twist.
