For an ensemble that's pared-down but can be dressed up or down in a ton of different ways, wear a brown pea coat and chinos. Want to tone it down when it comes to footwear? Complement this outfit with black and white low top sneakers for the day. As you slip into your 30s, you probably want to start dressing more like a mature gentleman. If that's the case, inspiration like this comes in very handy.
