PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a structured, ethnic-fusion crop top (blouse) likely made of raw silk or a stiff synthetic blend with metallic embroidery. It possesses high structural rigidity and low drape; it will not flow but rather contour tightly to the body. The surface has a semi-matte finish with specular highlights specifically on the gold chevron (zigzag) metallic threading. - **Key Features:** The sweetheart neckline and the precise alignment of the gold chevron stripes must be preserved. The thin spaghetti straps are essential structural elements. The cropped hemline sits above the navel. The side seams appear to have boning or stiff interfacing to maintain the shape, which must be replicated on the target. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Due to the garment's rigid nature, it must sit flush against the user's torso without bunching. Unlike the user's current loose outer shirt, this top requires a tension fit. The fabric must deform slightly around the bust curvature but maintain straight lines across the abdomen. The "Hand-on-Hip" pose (left side) requires the garment's hemline to rise slightly on that side due to torso tilt. - **Occlusion Handling:** The user's left hand (resting on the hip/waist) is a critical occlusion layer; the garment must pass *under* the thumb and fingers if the hemline reaches that low. The user's current outfit involves a long-sleeved jacket; since the target is sleeveless, the simulation must handle the transition of the shoulder/arm area, ensuring the new straps sit directly on the skin (masking out the old collar/sleeves). PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target environment is a nighttime street scene with mixed artificial lighting (cool overhead street lamps and bright, blooming background signage). The source garment's warm studio lighting must be neutralized. We must introduce cool-toned ambient occlusion in the shadows and sharp, high-contrast highlights on the gold embroidery to reflect the "point source" lighting of the street lamps. - **Color Calibration:** The maroon/magenta hue of the top needs to be color-graded to match the cooler, high-contrast night setting. The gold threads should pick up the ambient glow of the background lights (yellow/white) rather than studio softbox white. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's facial structure, expression, skin tone, and slicked-back hairstyle must remain frozen and pixel-perfect. - **Body Integrity:** The user's waist width and bust volume must be preserved. Do not warp the user's torso to match the slimmer silhouette of the source model. The synthesis must respect the user's anatomical boundaries while replacing the bulk of the current layered outfit with the skin-tight fit of the new garment.
