Consider teaming a navy blazer with white pants for a proper sophisticated look. To give your overall ensemble a more elegant feel, complement your look with a pair of olive suede desert boots. Think it's hard for teen boys to master semi-casual style? This combination is solid proof of otherwise.
Marrying a navy blazer with white pants is an on-point pick for a casually smart ensemble. Why not take a classier approach with shoes and introduce brown suede desert boots to the equation? As you're maturing from a kid to a teen guy, you probably want to start dressing more like a grown-up. In this case, ensembles like this are a fail-safe option.
