Hugh, maybe they dress like us! Lol! There hoods are much taller. It has nothing to do with them. The superstitious negro thought our disguises looked like Ghosts, one of the favorite things for the original to do was place a bladder hidden on their backs under the costume and ask the darky to give him some water, he would then drink the whole bucket and a few more. They then told the niggra that was the first drink he had since he was killed in battle at Shiloh!
