Vionnet eventually returned to Paris and trained with well known fashion houses. In 1912 she founded her own fashion house, "Vionnet". In the 1920s she created a stir by re-introducing the bias cut, an old technique for cutting cloth diagonal to the grain of the fabric. She developed techniques for managing the problems the bias cut caused. Bias cuts cling to the body and move with the wearer. Vionnet's use of the bias cut to create a sleek, flattering, body-skimming look would change women's clothing and carry her to the top of the fashion world.
