In the beginning, the pocket square was something only your grand-dad would wear, like a three-piece suit or a watch on a chain. Then the Earth cooled, and the accessory began to take on a bit of ironic hipness. In 2007, "Mad Men" came along and ruined it for everyone. And so it rested in peace until GQ Magazine acknowledged that "Mad Men" had killed the pocket square, which complicates things, since our general practice is to do the opposite of anything GQ endorses. At this point, reactionary dressing aside, we think a colourful, non-stodgy pocket square is great, as long as you don't overdo it by wearing a square AND a tie at the same time. Choose one or the other. You can guess which we'd pick. Shown: Howard Yount.
