Draping usually begins with a designer taking a basic garment and putting it on a dressmaker's model. The garment is generally already sewn into its core shape — for instance, a bias-cut dress would start out as a bias tube on the model. Next, the designer takes pieces of fabric and pins them to the garment where the drape is desired, which will give the final garment its shape. Most of the time the pinned fabric is not the same as the fabric that will be used for the final garment, but rather a similar cheaper fabric. This is because the fabric that's pinned on the dress will often be cut or marked on during the design process, which can be expensive with fine cloths.
