Mongolian traditional costumes were the basis for some of Queen Amidala's costumes in Star Wars IVXIVI: The Monkey Wars or something or other. Truth is I am not a fan of Star Wars, but visually the costume designs were pretty great for Amidala.
The image on the left is a traditional Mongolian woman's attire. Formal attire. Hmm.. I don't think headdress hair is actually made by horse-hair if i'm not mistaken. Unless you had really long hair. But even then it's bloody difficult to make these well-formed hard loops with them. You'd hafta go through many tubs gel wouldn't ya.
Very detailed info on Mongol costumes can be found here.
