The COSTUMAKERS general-purpose one-way separating zipper is designed for garments that need a full opening, including costumes, bustiers, and halter tops. It measures 50 cm (20 in) and uses #2.5 nylon coil teeth to stay lightweight while bending smoothly along curved seams during installation. Choose the Lightmauve shade for coordinated finishes, and stitch in with a zipper foot while keeping seam allowances clear of the coil and slider.
