Ravensbrück concentration camp
When prisoners first got to Ravensbrück, their hair was usually shaved off.  The SS took away their personal things, including their clothes.  Prisoners had to wear striped uniforms, which included a dress and a head scarf.  Later on in the war, when there were not enough uniforms, women were sometimes allowed to wear their own clothes.  However, they had to mark a big white "X" on the back of their clothes to show that they were prisoners.p. 76
