This casual combination of a dark brown barn jacket and a charcoal crew-neck sweater is extremely easy to throw together without a second thought, helping you look amazing and prepared for anything without spending too much time searching through your wardrobe. For extra fashion points, introduce brown suede casual boots to the mix. Seeing as temps are getting lower, this getup is a savvy idea for the transitional season. As a 30-year-old, you probably want to start dressing maturely. That's when looks like this come in very handy.
