What is the difference between satin and velvet?

Satin and velvet are both luxurious fabrics, but they differ in texture and construction. Satin is a smooth, glossy fabric typically made from silk, polyester, or nylon, characterized by its shiny surface and soft feel. In contrast, velvet is a thicker, plush fabric with a soft, raised pile, often made from cotton, silk, or synthetic fibers, giving it a rich and opulent appearance. While satin is often used for evening wear and lingerie, velvet is commonly found in upholstery and formal attire.
