Abstract: A pleated skirt to contact with side portions of the body of a wearer in which a width of each of the pleats in contact with side portions of the body of a wearer is larger than a width of each of the pleats in contact with front and back surfaces of the body of the wearer. The pleated skirt is produced by forming linear pleats in front and back pieces of fabric material by use of pleat pattern molding boards in which a width in right and left side portions is larger than a width in an intermediate portion and sewing up the front and back pieces of the fabric material at the side portions.
