Churidars
Churidars, or more properly churidar pyjamas, are tightly fitting trousers worn by both men and women in South Asia and Central Asia. They are a variant of the common salwar pants. Salwars are cut wide at the top and narrow at the ankle. Churidars narrow more quickly, so that contours of the leg are revealed. They are usually cut on the bias (at a 45 degree angle to the grain of the fabric) which makes them naturally stretchy. Stretch is important when pants are closefitting. They are also cut longer than the leg and finish with a tightly fitting buttoned cuff at the ankle. The excess length falls into folds and appears like a set of bangles resting on the ankle (hence 'churidar'; 'churi': bangle, 'dar': like). When the wearer is sitting, the extra material is the "ease" that makes it possible to bend the legs and sit comfortably. The word "churidar" is from Hindi and made its way into English only in the 20th century. Earlier, tight fitting churidar-like pants worn in in India were referred to by the British as Moghul breeches, long-drawers, or mosquito drawers.
The churidar is usually worn with a kameez (a form-fitted overshirt) by women or a kurta (a loose overshirt) by men, or they can form part of a bodice and skirt ensemble, as seen in the illustration of 19th century Indian women wearing churidar with a bodice and a transparent overskirt. Traditionally attired Kathak dancers, from northern India, still wear churidar with a wide skirt and a tight bodice; when the dancers twirl, the leg contours can be discerned -- as can be seen in many Bollywood movies featuring Kathak dancing.
