For as long as we’ve been walking the earth, we’ve been moving our bodies to express ourselves—variously with grace, verve, ferocity, style, attitude, elegance, and a studied pedigree. We gathered a wild array of dancers and models—moving in idioms and moods from ballet to Broadway, from the rave to the after-hours dance floor—and dressed them in an equally wide-open array of fashion encompassing ruffles and feathers, tulle and denim, leather and track pants; from elegant draping to a kind of balletcore-meets-street mash-up. Then we asked them only to move to the music, go with the flow—and simply dance like the whole world is watching.
