In winter, you can choose brown velvet with light gray trousers or jeans, and then wear a turtle neck with the same color as trousers, echoing up and down. In fact, a whole set of brown is also very handsome, which can be matched with Polo shirts and sneakers to show a casual look. You can also wear a shirt and tie to make yourself more gentleman. Note that you should learn to present your unique style with the mix and match style of sweaters and sneakers.
