There's no nicer way to brighten up a gloomy fall day than a seriously stylish look like this one. An ensemble like this will help any guy in his 40s upstage his peers.
For an ensemble that's city-style-worthy and casually sophisticated, try pairing a blazer with a navy sweatshirt. For something more on the dressier end to finish this ensemble, complement your outfit with black leather loafers. As the temperatures lower, you'll find that an outfit like this is perfect for fall. Wondering how your rotation should look as you age into your 40s? This combination is a perfect example.
