The combination of a grey overcoat and a dark brown turtleneck makes this a really put together ensemble. To give this ensemble a more laid-back aesthetic, introduce a pair of brown leather casual boots to the equation. Piecing together a cool look can be a bit nerve-racking and time consuming on its own. Enter extra cold temps into the equation, and the whole thing becomes all the more difficult. Luckily, this here is your winter outfit inspo. As a guy in his 40s, you'll love this combo.
