For a look that's super simple but can be modified in plenty of different ways, consider teaming a dark brown field jacket with chinos. In the shoe department, go for something on the dressier end of the spectrum with black leather chelsea boots. If you're after a stylish winter-to-spring transition look, this one is great. So if you're hunting for a nice yet mature combo for a 20-year-old gentleman, this just might be it.
