Sateen is a type of fabric that is made from cotton and has a smooth, lustrous finish. It is created using a weaving technique that gives it a soft feel and a shiny surface, similar to silk. Sateen is often used for bed linens, clothing, and home décor items due to its luxurious appearance and comfort. The fabric is typically heavier than regular cotton and has a slight sheen, making it popular for items like sheets and pillowcases. Sateen is also known for its durability and ability to resist wrinkles, making it a practical choice for everyday use in households and fashion.
