When the dress code calls for a polished yet cool ensemble, marry a black short sleeve shirt with dress pants. For something more on the sophisticated side to finish your getup, complement your outfit with a pair of dark brown suede loafers. This one is a savvy choice if you're picking out a standout look for awkward transition weather. As you reach your 30s, you want to start dressing more professionally. That's when inspiration like this comes in useful.
