This casual combination of a red sweatshirt and navy jeans is very easy to put together without a second thought, helping you look dapper and ready for anything without spending a ton of time digging through your wardrobe. If you need to easily spruce up your ensemble with footwear, introduce a pair of black and white leather loafers to your ensemble. As you're maturing from a kid to a teen boy, you probably want to look older than your age. That's when outfits like this come in useful.
