The term 'Lustrous COTTON' is a combination of two words, 'Sateen' and 'COTTON'. Sateen is a type of fabric that is made from COTTON fibers and has a glossy, smooth finish. It is often used in clothing and home decor items because of its softness and durability. COTTON is a natural fiber that is lightweight, breathable, and strong. It is also highly absorbent and can be dyed easily. Together, these two materials create a luxurious, lustrous fabric that is perfect for a variety of uses.
