Lanvin is a high fashion house, which was founded by Jeanne Lanvin. From 1923, the Lanvin empire included a dye factory in Nanterre. In the 1920s, Lanvin opened shops devoted to home decor, menswear, furs and lingerie, but their most significant expansion was the creation of Lanvin Parfums SA in 1924 and the introduction of My Sin in 1925 widely considered a unique fragrance, an animalic-aldehyde based on heliotrope, which would be followed by their signature fragrance Arpège in 1927. One of the most influential designers of the 1920s and 1930s, Jeanne Lanvin's skillful use of intricate trimmings, virtuoso embroideries and beaded decorations in clear, light, floral colors became a Lanvin trademark. While enjoying a revitalized reputation in luxury, Lanvin received mainstream press in the United States in May 2009 when Michelle Obama was photographed wearing a popular line of Lanvin's sneakers made of suede with grosgrain ribbon laces and metallic pink toe caps while volunteering at a Washington, D.C. food bank.
