In 1922, Lanvin collaborated with celebrated French designer Armand-Albert Rateau in redesigning her apartment, her homes and her businesses. (The living room, boudoir and bathroom of the apartment was reassembled in 1985 in the Musée des Arts Décoratifs, Paris.) For this domicile, Rateau designed some remarkable 1920–22 furniture in bronze. The pair developed a friendship, and Rateau came aboard Lanvin's empire as manager of Lanvin-Sport, also designing the Lanvin spherical "La Boule" perfume "flacon" for Arpège (originally produced by the Manufacture Nationale de Sèvres). To this day, Arpège perfume containers are imprinted with Paul Iribe's gold image (rendered in 1907) of Lanvin and her daughter Marguerite. Rateau also managed Lanvin-Décoration (an interior-design department, established 1920) in the main store on the rue du Faubourg Saint-Honoré.
