100% crisp cotton is a good choice for any season, and an even better one for comfort layering. Toss on a short-sleeve tee with a button-front closure with old-boy appeal or a little prep school flavor, and you’re more or less ready to go. If you’re more the geek chic type, try wearing it with a grandpa cardigan and ’40s style pair of slacks. Good shape comes easy with Rag & Bone. [$79 at forward by revolve]
