阳台黑裙欢快舞蹈

Create a realistic 10-second video of the woman in her black dress dancing happily on the balcony. She smiles beautifully, moves her hips and shoulders naturally, performs graceful hand movements and gentle turns. Her long ponytail and dress move naturally with every step. Use cheerful romantic music with a matching dance beat. Ensure perfect music synchronization, smooth realistic movements, and a joyful expression. Keep her face and full body visible throughout.
