Art Nouveau was an international style from 1890-1914 that emphasized unified design and innovative materials and forms. Key designers like Paquin in Paris and Worth created fashion for international clients. Paquin directed fashion sections at world's fairs to promote her couture house. Lucile also promoted her fashion through staged shows and dressing celebrities. Designs drew inspiration from natural forms and exotic cultures like the Ballets Russes. Poiret created simple silhouettes with lavish surfaces. Artists like Mucha and the Wiener Werkstätte collaborated with fashion. The style saw revivals in the 1960s and influenced modern designers.
