I think Terry Pratchett had it right. Female dwarves have beards and even the male dwarves have trouble identifying females. It might explain why they are so clannish. If you know who everyone is then you know if they are the same sex. Go to the big city and no telling who you are with.
DIVERGENT THOUGHT
Why are all hairy females in sci-fi sexy but in fantasy they are "ugly dwarves"?
