The salwar can be taken to mean loosely-fit pajama-like trousers, with an in-built string, at the waist level, for tying purposes.
The kameez can be described as a long shirt of tunic length, which might have short, long or no sleeves. It comprises of chaak (side seams below the waist-line) and usually reaches the knees which give the wearer greater freedom of movement.

On a female, the shalwar kameez ensemble is completed by wearing a dupatta/chunni, a loose scarf like a stole, which is either hung on the shoulder or slung across the neck.
