When Anna Wintour dedicates an entire issue of her beloved Vogue to the world the upcoming Olympic Games, you can assume that sports have officially been deemed worthy of the fashion world. But you didn't need a magazine to tell you that. Plenty of brands have long cashed in on their jock-happy ethos. This summer, Calvin Klein will take an interesting approach to the competition, with the introduction of their International Flag Collection. The brand takes their sexiest silhouettes—the brief and boxer-brief—and renders them with the patriotic pop of various flags from countries worldwide, including Spain, Italy, and Germany (as pictured here), so that no matter where you are, you'll always be rooting for your fellow countrymen as the games unfold on track and field this summer.
