/kloc-in the 0/9th century, in addition to the popular public ball, court ball continued. At the ball, women dressed in gorgeous costumes waited for the invitation of men with dignity and arrogance. The ball was held according to strict etiquette, and only Bologna, Waltz and Kadrill danced. Dance costumes are still bell-shaped skirts with thin skeletons, but the difference is that redundant frills and decorations are removed, which can show the graceful figure curves of women. The curtsy of male and female couples no longer squats like before, but only nods gently and quickly. A lot of complicated procedures were removed before and after the dance.
