This combination of a navy overcoat and navy chinos is hard proof that a pared down outfit doesn't have to be boring. Finishing off with a pair of dark brown leather chelsea boots is a fail-safe way to introduce a bit of flair to this getup. We recommend this one if you're on the lookout for a winter-appropriate look that's as stylish as it is practical. As you head into your 30s, you want to start dressing more maturely. In this case, combos like this are a life saver.
