Satin is a smooth, glossy fabric characterized by its luxurious finish and soft drape. Made from silk, polyester, or acetate, it features a distinctive weave that produces a shiny front and a dull back. Satin is commonly used for evening wear, bridal gowns, lingerie, and accessories like scarves, as well as in home décor for items such as drapes, pillowcases, and upholstery, offering a touch of elegance and sophistication.
