Satin is often mistaken for a fabric, but it's actually a type of weave that can be made from various materials, like silk, polyester, and nylon. The satin weave is characterized by its smooth, glossy surface and the way it reflects light, creating a luxurious appearance. This weave involves floating threads over others to create a high-shine finish and a soft, supple texture. Whether it's a silky cami or a viscose satin midi dress, the distinctive sheen and elegant drape of satin are due to the unique way the fibers are woven, not the material itself.
