For an ensemble that's extremely easy but can be flaunted in a myriad of different ways, consider wearing a grey cardigan and a white print crew-neck t-shirt. To introduce some extra definition to your outfit, finish with a pair of black leather derby shoes. So as you can see here, it's a kick-ass, not to mention spring-friendly, getup to have in your seasonal rotation. A reliable option for 20-year-old guys searching for a more professional look.
