An invisible zipper is a type of zipper designed to be concealed within a seam, making it nearly undetectable when closed. This feature allows for a clean and seamless look in garments, bags, and other fabric items. Typically used in clothing like dresses and skirts, the zipper is sewn in such a way that only the pull tab is visible. The construction of an invisible zipper involves a special type of zipper tape that is thinner and more flexible than standard zippers. This design enables the zipper to blend seamlessly with the fabric, enhancing the overall aesthetic of the item. Many sewing enthusiasts prefer invisible zippers for their ability to provide a polished finish.
