Gabrielle Bonheur "Coco" Chanel began selling women's clothing in 1914 after she expanded from a millinery shop that she opened in 1910. Early innovations credited to the Chanel label include the use of jersey fabric in women's clothing and the boxy jacket and skirt combination now known as the classic Chanel suit, which is worn by women the world over. She is responsible for moving women's fashion away from restricting corsets in favor of clothing that promoted freedom of movement and that relied on the principles of male dressing. The clothing uses European sizing.
