He pointed to the face and hands. The second requirement is looseness. The clothing must be loose enough so as not to describe the shape of the woman's body. One desirable way to hide the shape of the body is to wear a cloak over other clothes. However, if the clothing is loose enough, an outer garment is not necessary.
Thickness is the third requirement.
The clothing must be thick enough so as not to show the color of the skin it covers or the shape of the body. Curse them for they are truly cursed. Another requirement is an over-all dignified appearance. The clothing should not attract men's attention to the woman. It should not be shiny and flashy so that everyone notices the dress and the woman.
