Such essentials as a navy denim jacket and a white dress shirt are the ideal way to inject an air of rugged refinement into your casual fashion mix. Brown suede casual boots add a little edge to an otherwise dressy ensemble. In the colder months, when practicality is critical, it can be easy to surrender to a less-than-stylish outfit. This outfit, however, is a shining example that you totally can stay warm and remain stylish during the colder months.
