This off-duty pairing of a sweatshirt and a white and blue short sleeve shirt is super easy to pull together in no time flat, helping you look on-trend and ready for anything without spending too much time searching through your wardrobe. If in doubt as to what to wear on the shoe front, go with a pair of white leather low top sneakers. When leaves are falling down and autumn is in full swing, you'll love this ensemble as your uniform for unpredictable fall weather. Surely a good idea if we're talking style for teenage guys.
