This combination of a white double breasted blazer and jeans is impeccably stylish and yet it looks comfortable enough and apt for anything. Our favorite of an endless number of ways to finish off this look is with a pair of white and red slip-on sneakers. This here is proof that it is actually possible to survive the scorching heat, all while looking light and breezy. This combination shows how to keep killing in casual dressing as an over-50 gent.
