So as you can see, it doesn't require that much effort for a man to look stylish. Marry a navy overcoat with a white crew-neck t-shirt and you'll look awesome. If you wish to immediately up the style ante of your outfit with one single piece, finish off with a pair of brown suede tassel loafers. If you're over 30, take cues from looks like this to take a more mature direction in your style.
