PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a white cotton-jersey blend, likely with spandex content (bodysuit style). It possesses high elasticity and a matte finish. Unlike the user's current textured top, this material is smoother and absorbs light rather than diffusing it heavily. It requires tension mapping to show stretch rather than loose drape. - **Key Features:** The central pink graphic text ("LOS ANGELES 1989 California") is the focal point and must remain legible but naturally warped by the bust. The pink contrast piping/overlock stitching lines that contour the bodice are critical for defining the shape. The deep scoop neckline must be accurately reproduced. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Due to the user's crossed-arms pose, the garment physics must simulate compression. The fabric should appear pulled taut across the upper chest and disappear naturally under the crossed forearms. Since the source is sleeveless and the target is sleeved, the simulation requires generative in-painting of the user's skin on the shoulders and deltoids to replace the existing grey sleeves. The hemline must appear tucked into the existing tan trousers, maintaining the current waistline definition. - **Occlusion Handling:** This entails complex layering. 1. **Arms:** The user's crossed forearms and hands must completely occult the lower mid-section of the new top. 2. **Hair:** The dark, wavy hair falling over both shoulders must be segmented and layered *over* the white straps of the tank top. 3. **Accessories:** The red thread/bracelet on the left wrist remains the top-most layer. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target scene features harsh, high-contrast outdoor sunlight coming from the upper right. The studio-lit source garment must be re-relit to match. This involves casting hard shadows from the user's hair onto the white fabric and creating a deep ambient occlusion shadow where the arms cross over the chest. The white fabric should blow out slightly in the direct sun but retain texture. - **Color Calibration:** The "studio white" of the source must be temperature-shifted. It needs to adopt the warm, yellowish hue of the sunlight and pick up subtle green bounce light from the adjacent painted wall and staircase railing to integrate realistically. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's side profile, jawline, ear, and specific hair volume must remain pixel-perfectly frozen. No alteration to the facial expression or head orientation. - **Body Integrity:** Strict prohibition on body resizing. The user's shoulder width and arm thickness must remain identical. The skin tone generated for the newly exposed shoulders must flawlessly match the existing complexion of the face and hands.
