Such must-haves as a blazer and a green crew-neck sweater are the ideal way to infuse some manly refinement into your daily off-duty lineup. If you wish to easily play down this outfit with one piece, why not complete this outfit with black suede driving shoes? There's no nicer way to brighten up a dull autumn day than a kick-ass outfit like this one. Surely a great idea when it comes to style for 40-year-old men.
