Prompts used in the video:
1. Transform the model into a visibly plus size, full bodied woman with realistic weight distribution and natural anatomy. Significantly increase overall body volume, especially in the hips, glutes, thighs and lower abdomen, creating a soft and heavy silhouette. The waist should be wider and less defined, with natural belly fullness and gentle folds, avoiding a flat or sculpted look. Increase bust size proportionally, with natural sag and weight, consistent with a heavier body. Arms should be thicker, especially upper arms, with soft curves and realistic skin tension. Legs should be strong and full, with pronounced thighs and calves, showing natural body mass. Maintain realistic proportions, gravity and smooth transitions between body areas. Clothing must adapt naturally to the larger body, with visible fabric stretch, tension and folds where appropriate, without distortion or clipping. Preserve the original face, expression, pose, lighting and studio background. The final result should look like a real plus size woman, confident, healthy, photorealistic, fashion editorial quality, not exaggerated, not cartoonish.


2. Edit the woman’s body to appear extremely thin and very lean, with a high fashion runway body type. Significantly reduce body volume across the entire figure. Make the waist very narrow, hips slim and straight, and thighs thin with minimal curvature. Legs should appear long, slender and light. Arms should be very thin, especially upper arms and forearms. Reduce bust size noticeably to match the very slim torso. Create a sharp, elongated silhouette with minimal body mass, similar to a sample size fashion model. Maintain realistic anatomy, bone structure and natural proportions without distortion. Clothing should hang loosely on the body, emphasizing the lack of volume, with natural fabric drape. Keep the same face, expression, pose, lighting and background. The result should look like an ultra thin high fashion model, editorial photography, highly realistic.
