For a look that's pared-down but can be modified in a variety of different ways, try pairing a dark brown crew-neck sweater with a white long sleeve shirt. Complement this ensemble with a pair of tan leather sandals to easily amp up the cool of your outfit. You can bet this look is great when summer days set in. Laid-back ensembles for stylish gents in their 20s aren't actually that hard, as you can see.
