The hairstyle used by the two sisters is called the Squash Blossom Whorls, or Butterfly Whorls and were worn only by the young Hopi maidens to show that they were unmarried. This complex hairstyle was achieved by the maidens mother, who would wind her hair around a curved piece of wood to give it a round shape, then remove the wood frame.The Squash Blossom Whorl is often attributed to being the source of Star Wars character Princess Leia’s iconic hairstyle, as well as Mexican Revolutionary Clara de la Rocha, who also wore a similar style common amongst Soldaderas.
