A garment closure made of interlocking teeth attached to strips of fabric known as the zipper tape. Zippers were originally made of metal, but are now available with polyester or nylon molded teeth on a woven or knit polyester tape. Most zippers are attached to garments by stitching the zipper tape to the garment seam. Invisible zippers do not show once they are attached to the garment because the teeth of an invisible zipper are covered by the zipper tape and hidden in the seam of the garment. Zippers come in every size and color and can be used functionally or decoratively.
