Fine, very lightweight, machine-made net in which small mesh effects, usually hexagonal in shape, are seen. Uses include ballet costumes, bridal veils, dress goods, formal gowns and over-draping effects. Tulle is often used as an accent, to create a lacy, floating look. Tulle may also be used in underskirts or petticoats to create a stiff belled shape. Gowns are often puffed out with the use of several layers of stiff tulle. Tulle netting is also used to make veils, since it obscures the features of the face while allowing the wearer to see out.
