3D draping is a technique used in fashion design to create garments by arranging fabric directly on a dress form or mannequin. This method allows designers to visualize how the fabric falls and interacts with the body, helping them to make real-time adjustments to the design. It is often used to explore different styles, shapes, and silhouettes before finalizing a pattern. The process involves manipulating the fabric, pinning, and tacking it in place to achieve the desired look. 3D draping can be enhanced with digital tools, allowing designers to create virtual prototypes and experiment with various materials and textures without the need for physical samples.
