They had names like Bianca, Marina and Loulou, famously wore Halston, Gucci and Fiorucci, as well as Stephen Burrows and Giorgio di Sant'Angelo, and spent their nights doing the hustle, hooking up, making out and all sorts of activities that pushed the boundaries of propriety and, on occasion, legality. As the style pack moved from Europe to Gotham in the late Seventies, native and new New Yorkers took fashion from the runways to the disco dance floors. The epicenter was Studio 54, where WWD covered the shenanigans almost daily, from its opening night to Bianca Jagger's arrival on a white horse to Valentino's circus-themed birthday extravaganza. Yet Studio wasn't the hustle's only home. Nan Kempner also boogied up a storm with a busboy or two at Infinity and Regine's, Grace Jones belted out tunes at Les Mouches, and, in Paris, Kenzo and Karl Lagerfeld stayed out all night with Paloma Picasso at Club Sept in Paris. The energy was universal, and discos and roller discos became hotbeds of style, even if the focus wasn't always on fashion per se. "I lost my clothes getting in," an exhausted Joanna Dendel told WWD on Studio 54's opening night.
