There are several different types of silk fabrics, including silk chiffon, silk organza, and silk georgette, which all tend to be more lightweight and flowy. Silk satin, silk crepe, and silk velvet can be heavier and have more of a satin finish to them. Mikado silk is a popular type of choice that is ideal for structured dresses. Silk shantung is more coarse and can have a slightly different look.
