If you’ve ever attended a college football game, especially in the South, you’ve probably made an observation or two about what the students wear on game days. As a native of Baton Rouge, Louisiana (Go Tigers!), and now a resident of a very college-dense part of North Carolina, I’ve been privy to the attire of the college students in attendance more than a few times. For many years, they’ve gravitated toward the same simple outfit combination: a casual minidress and mid-calf or knee-high Western boots

I don’t know how or why this became the go-to game-day outfit, but I recognize the practicality. Football games are often hot—hence the minidress—and you’re probably going to do a lot of walking between the car you arrived in, your tailgate spot, and the stadium, hence the walkable Western boots. But it’s not an outfit combination that’s exclusive to college football stadiums, as Margot Robbie just proved while heading into West Hollywood hot spot The Bird Streets Club on a very warm day in L.A. over the weekend.
