of the back just below the shoulder or alternately one simple pleat on each side of the back. Jackets designed for active outdoor wear frequently have pleats (usually inverted box pleats) to allow for freedom of movement. Norfolk jackets have double-ended inverted box pleats at the chest and back. Skirts and kilts Skirts, dresses and kilts can include pleats of various sorts to add fullness from the waist or hips, or at the hem, to allow freedom of movement or achieve design effects. One or more kick pleats may be set near the hem of a straight skirt to allow the wearer to walk comfortably while preserving the narrow style line. Modern kilts may be made with either box pleats or knife pleats, and can be pleated to the stripe or pleated to the sett (see main article Kilts: Pleating and stitching). Trousers 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 bellows pockets. Pleated trousers were popular before World War II; fabric rationing during the war precluded the style, and flat front became the standard by necessity of cloth shortages.Pleated pants, especially of the double reverse pleat variety, were commonplace in the 1980s and 1990s, but by the late 2000s they had fallen out of favour. Pockets A bellows pocket is patch pocket with an inset box pleat to allow the pocket to expand when filled. Bellows pockets are typical of cargo pants, safari jackets, and other utilitarian garments. Pleated blinds The pleated blinds are curtains made of a dense fabric that folds up in an accordion when lifted. The model was developed in Germany in the middle of the 20th century. Today pleated blinds are popular all over the world due to their functionality, variety of design and effective protection from sunlight.
