Every bride knows that getting into a crystal-embellished or lace wedding dress with a full skirt and a train, after having your hair and make-up done, is a delicate procedure requiring the poise and balance of a prima ballerina! These zips are perfect for wedding, bridesmaid, and prom dresses that may require a little more ‘doing-up’ than usual. These extra-strong, no.5, YKK concealed zips won’t fail you. They’re longer and stronger than anything you can buy in the shops. The photos include a standard 22″ (56cm) dress-weight concealed zip for comparison. NB these zips require a narrow zipper foot similar to our adjustable narrow zipper foot or combination zipper/straight stitch foot. They cannot be installed with a normal invisible zip foot due to the size of the coil teeth.
