For an outfit that brings function and style, reach for a tobacco shawl cardigan and navy jeans. Introduce a pair of dark brown leather casual boots to your look et voila, the look is complete. During the winter months, when warmth is prized, it can be easy to surrender to a less-than-stylish outfit. But this outfit is a shining example that you can actually stay toasty and remain equally stylish during the winter months. As you go into your 30s, you want to start dressing like a grown-up. If that's the case, getups like this are a winning option.
