If you're on the lookout for a casual and at the same time on-trend outfit, try teaming a white and red and navy long sleeve shirt with a crew-neck t-shirt. Tap into some Idris Elba stylishness and introduce a pair of black leather casual boots to the equation. You can bet this ensemble will become your favorite when spring comes. When it comes to casual style for older gents, this combo looks great on almost any gentleman.
