A long sleeve t-shirt and black leather skinny jeans are the kind of a never-failing casual ensemble that you need when you have no extra time to plan an ensemble. Get a bit experimental on the shoe front and elevate your ensemble by wearing black and white ankle boots. In the colder months, when warmth is a must, it can be easy to settle for a less-than-stylish ensemble. But this ensemble is a striking illustration that you can actually stay toasty and remain equally stylish in the colder months.
