The influx of warmer weather may limit what we can wear outdoors (cheers to you, sweat glands), but long-sleeved shirts are still a viable summer option for many reasons. They level-up an outfit from laid-back to sharp for those days you want to go straight from beach to bar without turning you into a walking human oven. It's all about keeping things lightweight in cotton or viscose and ensuring you're wearing breathable, loose layers (read: unbuttonable). Try one of these long-sleeved looks on for size this weekend.
