The shalwar is loose pyjama-like trousers. The legs are wide at the top and narrow at the ankle. The kameez is a long shirt or tunic, often seen with a Western-style collar; however, for female apparel, the term is now loosely applied to collarless or mandarin-collared kurtas. The kameez might be worn with pyjamas as well, either for fashion or comfort. Some kameez styles have side seams (known as the chaak), left open below the waistline, giving the wearer greater freedom of movement.
