For a relaxed casual outfit, pair a yellow crew-neck t-shirt with black chinos — these two items play really great together. Put a relaxed spin on an otherwise sober getup by finishing with athletic shoes. Keep this combo ready to go when spring comes, and we guarantee you'll save a lot of time getting dressed on more than one morning. This combo proves that as a man in his 20s, you have a wide range of sartorial options.
