This combo of a white linen blazer and a light blue long sleeve shirt can only be described as devastatingly dapper and effortlessly refined. Don't know how to finish? Enter white low top sneakers into the equation to change things up a bit. This combination is also great if you're on the hunt for warm weather wear to make a boring day more bearable. All in all, a goofproof option if we're talking style for over-50 gentlemen.
