From Wikipedia, the free encyclopedia

A pleat is a type of fold formed by doubling fabric back upon itself and securing it in place. It is commonly used in clothing to gather a wide piece of fabric to a narrower circumference.

Knife pleats are used for basic gathering purposes, and form a smooth line rather than springing away from the seam they have been gathered to. The pleats have a 3:1 ratio- three inches of fabric will create one inch of finished pleat. Knife pleats can be recognized by the way that they overlap in the seam.

Box pleats are knife pleats back-to-back, and have a tendency to spring out from the waistline. They have the same 3:1 ratio as knife pleats, and may also be stacked to form stacked box pleats. These stacked box pleats create more fullness and have a 5:1 ratio. They also create a bulkier seam.

Rolled pleats create tubular pleats which run the length of the fabric from top to bottom. A piece of the fabric to be pleated is pinched and then rolled until it is flat against the rest of the fabric, forming a tube. A variation on the rolled pleat is the stacked pleat, which is rolled similarly and requires at least five inches of fabric per finished pleat. Both types of pleating create a bulky seam.

A cartridge pleat is a type of pleating by which a large amount of fabric is gathered into a small waistband or armscye without adding bulk to the seam. This type of pleating also allows the fabric of the skirt or sleeve to spring out from the seam. During the 15th and 16th centuries, this form of pleating was popular in the garments of men and women. Fabric is evenly gathered using two or more lengths of basting stitches, and the top of each pleat is whipstitched onto the waistband or armscye.

Clothing features pleats for practical reasons (to provide freedom of movement to the wearer) as well as for purely stylistic reasons.

Shirts and blouses typically have pleats on the back to provide freedom of movement and on the arm where the sleeve tapers to meet the cuff. The standard men's shirt has a box pleat in the center of the back just below the shoulder or alternately one simple pleat on each side of the back.

Pleats just below the waistband on the front of the garment are typical of many styles of formal and casual trousers including suit trousers and khakis. There may be one, two, three, or no pleats, which may face either direction. When the pleats open towards the pockets they are called reverse pleats (typical of khakis and corduroy trousers) and when they open toward the zipper, they are known as forward pleats.

Utilitarian or very casual styles such as jeans and cargo pants are flat-front (without pleats at the waistband) but may have box pleats in their pockets.
