For an outfit that's refined and GQ-worthy, team a turtleneck with charcoal dress pants. Tobacco desert boots are the simplest way to infuse a hint of stylish casualness into this look. During the colder months, when warmth is the priority, it can be easy to settle for a less-than-stylish ensemble. This ensemble, however, proves that you can actually stay warm and remain equally stylish in the colder months. So if you need fashion inspo for dressing as you step into your 40s, this getup is a good example.
