For a casually smart look, choose a red crew-neck sweater and a white dress shirt — these two items work really well together. A pair of grey leather casual boots brings just the right amount of casualness to this outfit. So so as you can see, it's a killer, not to mention spring-ready, look to have in your seasonal arsenal. As you're transitioning from a kid to a teen boy, you probably want to look a little older than your age. In this case, combos like this are a real lifesaver.
