Tap into sharp style with a dark green blazer and a white dress shirt. Finish off with a pair of black leather derby shoes and the whole look will come together brilliantly. During the winter season, when practicality is prized, it can be easy to surrender to a less-than-stylish ensemble in the name of convenience. But this ensemble is a shining example that you totally can stay cozy and remain equally stylish in the winter season. Take cues from outfits like this if you're on a mission to add more gravitas to your teenage wardrobe.
