Most Memorable Film Costumes: Cybill Shepherd as Betsy in Martin Scorsese’s, “Taxi Driver,” wearing a iconic red and white geometric patterned, low neck cut and tie waist, Diane von Furstenberg wrap dress. It optimized everything sexy and effortless about DVF’s designs and soon became a cult “70s happening.” As a fashion designer, Furstenberg is still best known for the wrap dress design (developed in 1974). It has since become an iconic style, still relevant today.
