In the late 1940s, American girls and boys dressed up in an unruly blend of saddle shoes and lederhosen to spice up Heidelberg, Germany. Young girls dressed in men’s flannels, jeans, and loafers march down the streets, drawing gasps from the locals. Old university caps, miniature Heidelberg sabersons, and military patches are reappropriating various Heidelberg customs into fashionable accessories, shocking the Germans. Invasion by the Americans!
