This combo of a button down blouse and black skinny jeans is proof that a safe casual ensemble doesn't have to be boring. If you're puzzled as to how to finish, add a pair of black suede ankle boots to the equation. In the colder months, when functionality is key, it can be easy to settle for a less-than-stylish ensemble in the name of convenience. But this ensemble is a striking example that you can actually stay cozy and remain seriously chic at the same time in the colder months.
