Lining refers to a layer of material placed inside a garment, bag, or other item to provide a finished look, added comfort, or protection. It can be made from various fabrics, such as cotton, silk, or polyester, and is often used in clothing like jackets, skirts, and dresses to enhance their appearance and durability. In addition to clothing, lining is also used in items like bags, shoes, and home furnishings such as curtains and cushions. It helps to conceal seams and raw edges, making the item more aesthetically pleasing while also improving its overall quality and longevity.
