A tutu is a short, stiff-waisted ballet skirt (parcel) that was born by gradually shortening the costume. It makes it easier to perform pirouettes, jumps, and complicated evolutions because it reveals the entire length of the ballerina's legs. This type of parka can be seen in many classical ballets, e.g. Swan Lake, The Nutcracker, or Coppelia. ³⁾
