This relaxed pairing of a tobacco overcoat and navy jeans is super easy to put together without a second thought, helping you look on-trend and prepared for anything without spending a ton of time digging through your closet. And it's a wonder how brown leather work boots can update an ensemble. In the colder months, when warmth is above all, it can be easy to surrender to a less-than-stylish ensemble in the name of practicality. This ensemble, however, is a bright example that you totally can stay toasty and remain equally stylish during the colder months. As you're going from your 20s to your 30s, you want to start dressing like an adult man. In this case, combos like this are a safe option.
