Gleaning their name from the nubuck material they're made from, bucks are a lightweight oxford made for stomping around in the summertime. Whether you rock them with a cotton suit, shorts, or light trousers, you can't go wrong. Sure, you can opt for a white pair and mess them up with grass stains and the like over the course of the season, but a nice brown pair of "dirty" bucks will go a long way in terms of what you can rock them with.
