Fascinating fashion original Iris Apfel holds forth on her nine decades of life and times in the late Albert Maysles’ (‘Grey Gardens’,’Gimme Shelter’) rousing salute to iconoclasm.

A joyous celebration of creativity and razor-sharp wit sustained into old age, as evinced by outspoken nonagenarian fashion icon Iris Apfel, ‘Iris’ also offers proof of Albert Maysles’ continued vitality as a documentarian. This character study proves as visually strong as it is verbally compelling. Iris likens assembling the elements of her signature “looks” — eclectic mixes of exotic fabrics and outlandish costume jewelry — to jazz improvisation. In contrast with the Maysles’ famous study of another fashionista, Edie Bouvier Beale in 1975’s “Grey Gardens,” there’s little distance between the way Iris consciously presents herself and the way the camera perceives her.

‘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.
