This polished combination of a white polo neck sweater and khaki dress pants is a must-try look for today's gentleman. Finishing with black suede loafers is an effective way to infuse a little edge into this look. As the weather starts to improve, it's time to shed those heavy winter layers and opt for an ensemble that's lighter, like this one here. If you want people to see maturity in you as a teenage boy, a look like this is a solid bet.
