As you can see here, it doesn't take that much work for a man to look on-trend. Wear a navy double breasted blazer with a white crew-neck t-shirt and be sure you'll look awesome. If you need to instantly tone down your outfit with footwear, why not complete this look with white and navy athletic shoes? This combo is a great inspiration to anyone who was doubtful about donning casual outfits as a gent over 40.
