楼梯上的黑裙动态人像

Create a realistic 10-second full-body video of the same woman wearing an elegant, fitted black mini dress and black high heels. She stands gracefully on the stone staircase, gently adjusts her long wavy hair, takes a few natural steps forward, smiles beautifully, and moves confidently with subtle feminine movements. Realistic human body motion, natural facial expressions, smooth camera movement, cinematic lighting, and high-quality details. Keep her original face and identity unchanged.
