Wear a white knit turtleneck with light blue skinny jeans for comfort dressing with a city style finish. If you want to easily smarten up your look with footwear, add a pair of white print leather low top sneakers to the equation. Keep this getup in your front hall closet when spring arrives, and we guarantee you'll save a lot of time trying to pick out what to wear on more than one morning. Off-duty getups for 20-year-old gentlemen aren't actually that hard, as you can see.
