Lanvin is a French fashion house that was founded in 1889 by Jeanne Lanvin. It started as a small hat shop in Paris and later expanded into women's clothing, men's clothing, children's clothing, and accessories.

Jeanne Lanvin's early designs were heavily influenced by the Art Deco movement, and she quickly gained a reputation for her delicate fabrics and intricate embroideries. She was particularly known for her use of rich colors, such as the signature "Lanvin blue."

In the 1920s and 1930s, Lanvin became a leading name in haute couture, and her designs were worn by some of the most fashionable women of the time, including Coco Chanel and the Duchess of Windsor. After Jeanne Lanvin's death in 1946, her daughter, Marguerite, took over the company and continued to expand the brand.

Today, Lanvin is known for its elegant and sophisticated designs, with a focus on luxurious materials and craftsmanship. The brand offers a range of men's and women's clothing, shoes, bags, and accessories, as well as a line of children's clothing.

Lanvin's men's clothing line includes tailored suits, casual wear, and sportswear, all featuring the brand's signature attention to detail and high-quality materials. The brand's children's line, Lanvin Petite, offers stylish and playful clothing for babies and children up to 14 years old.
