White skirt rides up as she walks away

You’re looking at the back of someone wearing a tight white skirt that rides up as they walk. The fabric bunches and moves with their steps, revealing the shape of their hips and lower back. There’s a strong light source behind them, making the scene glow and casting shadows. The person’s arms are visible, one slightly raised, and they’re moving away from the camera. The setting seems casual, maybe outdoors or in a bright room. The focus is entirely on the movement of the skirt and the body beneath it. No one else is clearly in frame, just the person walking off. It’s a candid, unposed moment caught on camera — not staged, just happening.
