It's called happy hour, not "rumpled undone suit at the end of a long day" hour. So go for something that's a little more casual, but still sharp and stylish. Trousers, a light sweater, a denim jacket, and a glass of Jim Beam Black® in your hand will help you nail that whole effortlessly cool vibe.
