If you're after a casual yet on-trend outfit, wear a blazer with cargo pants. Add a pair of dark brown leather double monks to this outfit to avoid looking too casual. In the colder months, when warmth is everything, it can be easy to surrender to a less-than-stylish ensemble in the name of practicality. However, this ensemble is hard proof that you can actually stay comfortable and remain stylish in the colder months. A great ensemble as you shift into your twenties.
