bias cut means: Bias cuts means “be cut on grain”. The bias cut positions the pattern at 45 degrees on the woven fabric, rather than following the lines of the weave. This angle gives the fabric more elastic stretch. The ‘warp and ‘weft threads are more prominent at the bias cut. It is used to accentuate body lines and create fluid curves and soft drapes. Madeleine Vionnet, a 1920s fashion icon, championed the bias cut and it became John Galliano’s favorite style. (in Fashion Dictionary)
