Make a grey suit and a dark green waistcoat your outfit choice if you're going for a sleek, stylish ensemble. Finishing off with tobacco leather double monks is a guaranteed way to infuse a touch of stylish effortlessness into your look. When it's one of those dull fall days, sometimes only a kick-ass outfit like this one can get you to face the outside world. Certainly a wonderful idea if we're talking fashion for 50-something gents.
