In the winter of 2017, a young woman called Vida Movahed stood on top of a utility box on Revolution Street, a busy artery of central Tehran, and dangled her white headscarf on a stick.Soon, more women launched similar protests, and their movement took the name of where it all began: #TheGirlsofRevolutionStreet.When I lived in Tehran in my early 20s, writing a TIME column called “Lipstick Jihad,” we used to flout the rules by wearing brilliant colors and tighter and shorter overcoats, pushing against the gloomy black and navy of official dress codes, and bringing some individuality within the bounds of an attire that was meant to erase distinctiveness.Last winter, instead of the usual dreary billboards of a pious woman in black chador with some hectoring message about modesty, a panoramic image went up over Modarres expressway in Tehran of a woman in a minimalist, sport hijab sprinting up a mountain, with the words “you chart the path.#findyourself.” At this writing, an estimated 400 Iranian protesters have been killed by security forces, though some human-rights groups put the number higher, and judicial authorities are seeking harsh penalties for some of those detained."
