Churidars or more appropriately churidar pyjamas are snugly fitting trousers worn by both men and women in South Asia. Churidars are an alternative of the common salwars. Salwars are cut broad at the top and slender at the bottom or pauncha. Churidars narrow more rapidly, so that contours of the leg are shown. They are usually cut on the bias, creating them as expected stretchy. Stretch is important when pants are body-hugging. They are also longer than the leg and at times finish with a tightly fitting buttoned or zipped cuff at the ankle. The surplus length fall into folds and become visible like a set of bangles resting on the ankle from where it derives its name churidar meaning bangle looking.
When the wearer is sitting, the extra material gives relaxed comfort that makes it possible to bend the legs and sit at ease. The word churidar is from Hindi language and made its way into English language only in the 20th century. Previously, tight fitting churidars worn in India were known as Moghul breeches, mosquito drawers, long-drawers etc by the British.
The churidar is usually worn with a kameez (tunic) by women or a kurta (a loose shirt) by men.
