Drawing fashion tip: This example shows the difference in wool, silk and taffeta and how they drape. Wool is stiff, but fluid, silk very fluid, and taffeta has a lot of body so it’s more architectural and stiff. There is also a center line to the body which curves with the torso. Use this center line to align your seams, and/or garment details. Always remember the shape and movement of the body underneath. The clothes only move because the body does.
