A tan trenchcoat and jeans matched together are a savvy match. If you need to easily step up this outfit with one single item, why not introduce a pair of double monks to the equation? On not-so-chilly days, you can sport this easy-to-transition outfit and look absolutely amazing. As you're transitioning from a kid to a teenage guy, you probably want to start dressing more maturely. If that's the case, getups like this are a solid bet.
