Prompt

Animate this white oversized crew neck T-shirt and matching white shorts as if worn by an invisible female character. The garments should walk in place with a natural and rhythmic walking cycle, simulating a treadmill-like motion. Fabric should move realistically with each step, showing subtle bounces and shifts caused by invisible body movement underneath. The camera is fixed in front view, centered at chest height. Background must remain solid chroma key green throughout the animation. Use the given first frame as the starting pose and maintain the same style, lighting, and proportions.
