If you're searching for a laid-back yet sharp look, wear a turtleneck with khaki jeans. For something more on the off-duty end to round off this outfit, complement your ensemble with a pair of light blue athletic shoes. So as you can see, it's a dapper, not to mention spring-friendly, combination to keep in your transeasonal collection. If you're often not sure how to dress appropriately for your age, this combo is a practical example.
