This laid-back pairing of a grey hoodie and charcoal sweatpants is a fail-safe option when you need to look nice in a flash. Breathe an element of refinement into this outfit by rounding off with black and white canvas low top sneakers. And if you're on a mission for a knockout look that transitions easily into spring, this is it. This is a wonderful example of how to dress with style as you go through your adolescence.
