The term 'Kilt Fold' is a type of pleating used in traditional Scottish kilts. It is a method of folding the fabric of the kilt into pleats, which are then sewn together to create a tailored look. The pleats are usually stitched down the center of the back of the kilt, and the pleats can be either box or knife pleats. The Kilt Fold is a popular style of pleating for kilts, as it creates a neat and tidy look.
