For a laid-back and cool outfit, wear a navy denim jacket with a turtleneck — these two items work beautifully together. When this outfit is just too much, dial it down by finishing off with a pair of brown leather work boots. During the colder months, when warmth is the priority, it can be easy to surrender to a less-than-stylish look in the name of convenience. However, this look is a practical illustration that you can actually stay snug and remain equally stylish during the colder months.
