For a laid-back and cool ensemble, rock a navy field jacket with black chinos — these pieces go wonderfully together. Why not take a more relaxed approach with footwear and add white and navy leather high top sneakers to the mix? As you can see, this look is a really smart pick, especially for awkward fall weather, when the temperature is dropping. Relaxed outfits for stylish men in their 40s aren't actually that hard, as you see here.
