On his hugely popular fashion blog Advanced Style, photographer Ari Seth Cohen has introduced readers to some of the world’s most fashionable, fabulous, inspiring women, including Iris Apfel and Linda Rodin. The blog, which features stylish women over 50, has been so successful since it’s founding in 2008 that it has since produced a book and now a documentary film of the same name. Fans come to Advanced Style for the fashion and the flamboyance, but the blog’s commentary on society’s fixation on youth and beauty has been just as influential: even Vogue Italia called Advanced Style less a street-style blog than "a sociological treatise" on ageing and identity. For those readers of Advanced Style who long to know more about the subjects of Mr. Cohen’s photos, the new film is an absolute joy. It delves into the lives and backstories of seven of the blog’s most beloved subjects, including Joyce Carpati, who at 82 must be the world’s most elegant woman.
