实际提示词：

```text
Use case: identity-preserve apparel edit. Image 1 is the exact white graphic T-shirt garment reference. Image 2 is the edit target and sole reference for the fictional adult male model. Generate a realistic full-body catalog photograph of the same man from Image 2 wearing the T-shirt from Image 1. Change only the upper garment. Preserve his face, short black hair, body proportions, front-facing pose, hands, charcoal trousers, white sneakers, pale gray studio background, framing, and even light. Preserve the white crew-neck short-sleeve T-shirt's silhouette, orange Sunday lettering with small black afternoon text, and the seated-person/orange illustration, at faithful relative positions and colors. Make print and fabric drape naturally over the torso; no redesign, extra letters or logos. Keep his entire head and both shoes visible. No hanger, hook, mannequin, extra person, props, added captions or watermark.
