For an ensemble that's worthy of a modern sartorially savvy guy and casually smart, wear a yellow hoodie with grey dress pants. Finishing with a pair of low top sneakers is a simple way to introduce a dash of stylish effortlessness to this ensemble. A practical example of transitional fashion, this look is perfect this spring. So if you're scouting for a good-looking yet age-appropriate getup for a young guy, this one is great.
