Lanvin is a high fashion house founded by Jeanne Lanvin.

Lanvin made such beautiful clothes for her daughter 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.

From 1923, the Lanvin empire included a dye factory in Nanterre. 1920s, Lanvin opened shops devoted to home decor, menswear, furs and lingerie, but her most significant expansion was the creation of Lanvin Parfums SA in 1924 and the introduction of her signature fragrance Arpège in 1927, inspired by the sound of her daughter's practising her scales on the piano. A later perfume, "My Sin," is widely considered one of the most unique fragrances, an animalic-aldehyde based on heliotrope.

One of the most influential designers of the 1920s and '30s, Jeanne Lanvin's skilful use of intricate trimmings, virtuoso embroideries and beaded decorations in clear, light, floral colors became a Lanvin trademark.
