tutu

A colourfully decorated classical ballet tutu, on a dress form

A tutu is a dress worn as a costume in a classical ballet performance, often with attached bodice. It may be made of tarlatan, muslin, silk, tulle, gauze, or nylon. Modern tutus have two basic types: the Romantic tutu is soft and bell-shaped, reaching the calf or ankle; the Classical tutu is short and stiff, projecting horizontally from the waist and hip.
