For her 30th birthday, Jeanne Lanvin wanted to give Marguerite, a unique perfume developed by renowned perfumer André Fraysse. When Marie-Blanche smelled this composition for the first time, featuring notes of Bulgarian rose, Grasse jasmine, honeysuckle, and lily of the valley, she exclaimed: "It's like an arpeggio." It was a complete success, and Arpège became the ultimate symbol of Jeanne's love for her daughter.
After Jeanne Lanvin passed away, her daughter Marie-Blanche became president of the company and continued to design collections until 1950. Several designers succeeded her with the ambition of keeping the brand's expertise, state of mind, and excellence intact.
