For an outfit that's pared-down but can be modified in many different ways, reach for a red and black long sleeve shirt and jeans. Take your outfit a whole other path by finishing off with a pair of white leather high top sneakers. So if it's a blazing hot summer day and you want to look sharp without putting in too much work, this ensemble will do the job in next to no time. Ideal for a 20-year-old gentleman if you want to present a mellow spirit.
