This casual combination of a red and white long sleeve shirt and a crew-neck t-shirt is super easy to put together without a second thought, helping you look awesome and prepared for anything without spending too much time combing through your closet. You could perhaps get a bit experimental in the shoe department and dress up your ensemble with a pair of black leather dress boots. During the winter months, when warmth is essential, it can be easy to surrender to a less-than-stylish getup in the name of practicality. But this getup is a good illustration that you can actually stay comfortable and remain equally stylish during the winter months. On a mission for dressing ideas for 30-year-old gents? This combo is great inspo.
