It really doesn't get much more textbook-autumn than a Fair Isle sweater. Or a Fair Isle sweater vest. This one's got a deep V neckline with ribbed trim, fully fashioned from soft merino wool... which makes it a little less rough-hewn than the Scottish classic it's inspired by. We loved this Fair Isle pattern so much that we made a matching beanie and scarf (although we aren’t saying you necessarily need to wear them all at once.)
