For a laid-back and cool ensemble, consider wearing a white long sleeve shirt and black ripped skinny jeans — these two items play really good together. Add a pair of white low top sneakers to the equation to completely switch up the outfit. During winter, when comfort is top priority, it can be easy to settle for a less-than-stylish look in the name of functionality. This look, however, is a vivid example that you can actually stay toasty and remain stylish during winter. If you're not sure how to dress as a 20-something guy, this combination is a great illustration.
