This cool and casual ensemble is really pared down: a white and blue long sleeve shirt and beige shorts. Introduce a pair of low top sneakers to this outfit and off you go looking dashing. So if it's a roasting hot summertime afternoon and you want to look dapper without putting in too much work, this look will do the job in next to no time. Relaxed getups for stylish teenage guys aren't actually that hard, as you see.
