On Monday evening, T Magazine held its annual party to help kick off the Salone del Mobile design fair in Milan. For the sixth year, guests flocked to Villa Necchi Campiglio, the 1935 Rationalist-style home designed by the Italian architect Piero Portaluppi. But this year, the cause for celebration was twofold: The event also marked the magazine’s 20th anniversary, and to honor the occasion, T’s editor in chief, Hanya Yanagihara, commissioned the Parisian multidisciplinary artist Ramdane Touhami to oversee the party’s design.
