The costumes worn by the KKK members is very distinct. They are known to wear long white robes that cover their arms and legs and usually cover even their feet so that no one can see their shoes. They also wear a tall white pointed hat on their heads and a white sheet over their heads with holes in them for their eyes nose and mouth. They wear these costumes that cover most of themselves so that people cannot see them.
They would not be able to identify these members. It is not known how the Klan members came up with their white conical shape costumes. It is only believed that they wore these costumes so that people could not identify them and they would not get in trouble with the law.
