This combination of a grey short sleeve shirt and jeans combines comfort and utility and helps you keep it clean yet current. Complement this look with a pair of black leather low top sneakers and ta-da: this getup is complete. This combination is also great if you're scouting for hot weather wear to make a boring day more tolerable. Those who are dubious whether you can still pull off modern casual outfits as you get older, this combo should answer your question.
