For a casually stylish look, reach for a blue shirt jacket and a white crew-neck t-shirt — these pieces play pretty good together. For something more on the smart end to complete your outfit, add dark brown leather brogues to the equation. Keep this ensemble in mind when spring comes, and we promise you'll save a lot of time getting ready on more than one occasion. This getup illustrates that as a guy in his twenties, you have a vast array of style options.
