Elegant Woman in Black Dress Showcases Graceful Movement in Grand Palace Setting

Generate a video in the style of a luxury clothing brand. The most important thing is not to change the facial features and body shape, make the video smooth and graceful. Do not change the facial expressions; the face should remain cold. The most important thing is to convey all the lightness of the dress; do not change the outfit yourself, but add lightness and grace to it. Let the action take place in a ballroom in a palace; the ball, candles, chandeliers.
