If you're a fan of casual combos, then you'll like this combination of a trenchcoat and black skinny jeans. To give this outfit a classier aesthetic, add a pair of brown chelsea boots. There's no nicer way to brighten up a dull autumn afternoon than a kick-ass outfit like this one. As you're approaching your 30s, you probably want to start dressing like a grown man. If that's the case, ensembles like this are a safe option.
