How do you ensure realistic costume and fabric drapery on comic characters, considering different materials?

To draw realistic clothing, understand how different fabrics (cotton, silk, leather, armor) drape, fold, and wrinkle according to their material properties, the underlying body's form, and gravity. Observe tension points where fabric pulls tight and compression points where it bunches. Pay attention to how light interacts with different textures, as this greatly enhances the realism of the material and helps define the form underneath.
