"Married women part their hair in the middle and plait it like a rope on either side, bringing it together behind; the smaller the tresses, the more beautiful it is considered. Unmarried women wear another plait at the back of their heads. On the top of their tresses they wear strings of pearls (or beads) or coral, called dum-che, fastened to the hair by a silver hook. To the lower end of their tresses they attach strings, seven or eight inches long, of beads or coral, which hang on the shoulder; they are called do-shal." (p. 224-225).
