This combo of a navy crew-neck sweater and jeans is on the off-duty side but guarantees that you look stylish and incredibly sharp. Clueless about how to round off? Introduce a pair of white and brown high top sneakers to the equation to change things up a bit. So if you're after a kick-ass look that will take you from winter to spring, this one is great. Perfect for a teen if you want to project a laid-back image.
