Shalwar
From AmtWiki
These are narrow at the ankles and widen as they go up the thigh. Quite a few have survived from the late 16th and 17th centuries. Shalvar are often made of the same kinds of fabrics as the entari, but they should NOT match."
In some of the accompanying pictures you can see that some shalvar are made much longer than the actual woman's leg, and of very soft fabric that pools around the leg."
