Along with the stripes, Kors also showed mod, Mary Quant-esque coats and dresses in punchy blues, arresting yellows and abstracted black and white houndstooth.
Combined with nylon (a Du Pont invention from 1939), Spandex allowed the production of tights with no garter or stocking belt, which in turn meant designers like MaryQuant could take the hemline of the skirt way up.
