PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a wrap-style crop top, likely made of cotton or a viscose blend. It features a matte finish with low reflectivity. The physics engine must simulate "tension" rather than flow, as the garment relies on being tied/wrapped around the torso. It should exhibit slight creases at the wrap crossover point but generally sit flush against the skin. - **Key Features:** The intricate red and orange floral pattern on the forest green background must be preserved without distortion. The deep V-neckline created by the wrap, the spaghetti strap halter-neck mechanism, and the cropped hemline (exposing the midriff) are the defining structural elements to transfer. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Unlike the target's current loose, structured button-down, the new garment is form-fitting. The simulation must generate natural skin texture for the abdomen/midriff area, as the source is a crop top and the target is currently fully covered. The fabric should stretch slightly across the chest due to the target's right arm reaching forward toward the railing, and sit tighter on the left side where the arm is relaxed. - **Occlusion Handling:** The target's long black hair falls over both shoulders and heavily obscures the upper chest area. The hair mask is critical; the new garment must be rendered *under* the hair strands. The thin gold necklace and the black bag strap on the left shoulder must also be segmented and layered on top of the new green fabric. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target environment is a shopping mall with diffuse, cool-toned, multi-source artificial lighting (high ambient occlusion). The studio lighting on the source garment (directional and warm) must be neutralized. Shadows on the new garment should be soft and spread out, matching the lack of hard shadows in the mall scene. - **Color Calibration:** The source garment's warm green tone needs to be slightly cooled (desaturated of yellow hues) to match the blue-tinted white balance of the mall environment so it doesn't look like a "sticker" placed on the image. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's face, specifically the eyes behind the glasses, the nose, mouth, and jawline, must remain completely frozen. The glasses frames must not be warped or obscured by the new strap lines. - **Body Integrity:** The generation of the exposed midriff must strictly adhere to the user's existing waist width and skin tone derived from her face and hands. Do not slim the waist or impose the source model's abdominal muscle definition onto the target user; the body shape must remain authentic to the User Image.
