The term 'closure for loose clothing' can be summarized as a SEAM, which is a line of stitching that holds two pieces of fabric together. Seams are commonly used in the construction of clothing and other items made from fabric, and they provide a secure closure that prevents the fabric from coming apart. Seams are usually created by sewing two pieces of fabric together with a needle and thread, but they can also be created using other methods such as heat sealing or gluing. Seams are an important part of garment construction, as they provide strength and structure to the finished product.
