For a look that's pared-down but can be flaunted in a multitude of different ways, team a grey turtleneck with white jeans. On the footwear front, this look pairs nicely with black and white canvas low top sneakers. As the weather starts to improve, it's time to get rid of those heavy winter clothes and choose something lighter, like this ensemble here. This combo shows how to wow in casual dressing as a 20-year-old man.
