satin
[U] Uncountable
This term evokes a specific sensory experience of coolness and slipperiness. It suggests luxury, elegance, and a high-sheen finish that reflects light sharply, often associated with formal evening wear or high-end lingerie. When used as an adjective, it describes a texture that is exceptionally smooth to the touch. It differs from silk in that satin refers to the weave rather than the fiber, meaning a satin fabric can feel synthetic and stiff or soft and fluid depending on the material used.
Used as a mass noun when referring to the fabric material itself, such as buying three yards of satin.
