IRIS pairs legendary 87-year-old documentarian Albert Maysles with Iris Apfel, the quick-witted, flamboyantly dressed 93-year-old style maven who has had an outsized presence on the New York fashion scene for decades. More than a fashion film, the documentary is a story about creativity and how, even in Iris’ dotage, a soaring free spirit continues to inspire. IRIS portrays a singular woman whose enthusiasm for fashion, art and people are life’s sustenance and reminds us that dressing, and indeed life, is nothing but an experiment.
