Make a white and black print hoodie and a white crew-neck t-shirt your outfit choice for a relaxed ensemble with a city style twist. Make a bit more effort with shoes and add beige canvas low top sneakers to the equation. Keep this combo in your front hall wardrobe when spring comes, and rest assured, you'll save a ton of time getting dressed on more than one morning. All in all, a good demonstration of relaxed casual fashion for 20-year-old gentlemen.
