If the mere mention of geometry has you flooded with memories of ninth grade math class and all that graph paper, you can put down that calculator now because we're actually talking about fashion.
Geometry has moved out of the classroom and onto the runway in the form of graphic prints that were all the rage for fall: Prada's mod dresses, while replete with rectangles, were anything but square; Issey Miyake's coats featured three-dimensional-looking cubes; both Marni and Hermes had southwestern hints to their knee-length dresses; and Rodarte's grey, black and white diamond-patterned apron dresses also referenced the tribal trend.
