For an outfit that's street-style-worthy and effortlessly elegant, try pairing an olive shirt jacket with a white vertical striped long sleeve shirt. Up the formality of this outfit a bit by slipping into black leather chelsea boots. The much awaited the spring season calls for neat combinations just like this one. As you pass the big 3-0, you probably want to start dressing like an adult. That's when combinations like this are a foolproof option.
