A beige trenchcoat and a navy blazer are absolute staples if you're putting together a refined wardrobe that matches up to the highest men's style standards. Introduce a pair of dark brown suede loafers to the equation and the whole look will come together quite nicely. Nothing like a knockout outfit to cheer up a gloomy autumn afternoon. As you're going from your 20s to your 30s, you want to start dressing more like a mature gentleman. That's when outfits like this come in useful.
