When did Coco Chanel start her business?

Coco Chanel started her business in 1910. That year, she opened her first shop named "Chanel Modes" in Paris, originally as a millinery (hat-making) boutique at 21 Rue Cambon. Her success in millinery led to expansion into clothing by 1913, and she became a major fashion designer known for her elegant, simple styles that revolutionized women's fashion in the 20th century.
