Reach for a grey wool harrington jacket and black chinos for both on-trend and easy-to-wear outfit. Complete this outfit with dark brown suede chelsea boots for a masculine aesthetic. As you can see here, this combination is a really wonderful choice, especially for unpredictable fall weather, when the temps are getting lower. As you head into your 30s, you probably want to start dressing like an adult. If that's the case, combos like this prove useful as a source of inspiration.
