Layer over your favorite summer dress or a crisp shirt-and-tie combination—The Drive Me Crazy Knitted Vest is a light-gauge knit sweater-vest that does as you wish, and then some. The slim, summery fit is as light to the touch as it is on the body, owing to the merino-and-cotton-blend yarn, with an intarsia Pleasing logo and car graphic for a moment of whimsy.
