Try teaming a brown overcoat with a light blue long sleeve shirt if you seek to look seriously stylish without exerting much effort. Add black suede low top sneakers to the mix to have some fun with things. During the colder months, when comfort is imperative, it can be easy to settle for a less-than-stylish ensemble in the name of convenience. But this ensemble is a striking illustration that you can actually stay snug and remain stylish at the same time during the colder months. A great combo to demonstrate the world your maturity even as a 20-year-old gentleman.
