One great fitting suit is all you really need for job interviews, formal functions, and almost all weddings. A gray flannel or classic navy blue goes for miles, and you can break it apart to rock just the pants or the jacket. This version from UNIS is unstructured, meaning there's virtually no padding to add bulk to the shoulders, but still made of great fabrics and wears easy. So you'll look completely comfortable despite the fact that you're outdressing every other dude at whatever party you're at. Get it in, Don Draper.
