Lanvin is a high fashion house founded by Jeanne Lanvin. Lanvin made such beautiful clothes for her daughter Marie-Blanche that they began to attract the attention of a number of wealthy people who requested copies for their own children. Soon, Lanvin was making dresses for their mothers, and some of the most famous names in Europe were included in the clientele of her new boutique on the rue du Faubourg Saint-Honoré, Paris. 1909, Lanvin joined the Syndicat de la Couture, which marked her formal status as a couturière.
