PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a quilted jacket (likely cotton batting fill). It possesses high structural rigidity and volume compared to the user's current thin fabric top. It should not drape fluidly like silk; rather, it must maintain a semi-stiff, padded appearance. Light diffusion should be matte, but with high-contrast ambient occlusion in the vertical quilting grooves to emphasize depth. - **Key Features:** The repeating tiger print pattern and vertical quilting stitch lines are non-negotiable. The contrasting blue-and-white patterned lining visible at the rolled-up cuffs must be preserved. The mandarin/stand collar and the patch pockets near the hemline must be rendered with 3D depth, not flat textures. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Due to the user's leaning pose against the sofa, the jacket must exhibit "volume offset"—it sits further from the skin than the current shirt. On the user's left side (resting on the sofa), the shoulder structure must remain defined but elevated slightly due to the arm position. The fabric should crease sharply at the inner left elbow and bunch slightly at the waist due to the jacket's stiffness. The hemline should fall straight, breaking slightly only where it contacts the right thigh. - **Occlusion Handling:** CRITICAL: The user has long, dark hair cascading over the left shoulder and the right side of the chest. This hair must be segmented and layered *over* the new jacket. The user's right hand/wrist (wearing bangles) interacts with the thigh; the jacket sleeve (with the rolled cuff) must end appropriately at the wrist, potentially obscuring the bangles unless the sleeve is simulated as slightly pulled back. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target environment features multiple warm, overhead point lights (tungsten/yellow hue) creating a high-contrast scene. The source garment is lit by flat, cool studio light. The transfer must apply a warm color cast (temperature shift to ~3500K) to the pink jacket. Shadows must be cast downwards from the collar and buttons. - **Color Calibration:** The bright bubblegum pink of the source needs to be desaturated slightly and darkened to match the ambient exposure of the lounge. Bounce light from the white leather sofa must be calculated, adding a slight soft white fill to the user's left side (viewer's right) of the jacket. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** Absolute freeze on the user's facial geometry, skin texture, makeup, and hair flow. The neckline transition from the new mandarin collar to the user's neck must be seamless without blurring the jawline. - **Body Integrity:** Strictly forbid any slimming, warping, or "beautification" of the user's torso or waistline. The lower body (grey jeans) and the position of the legs must remain pixel-perfectly identical to the original image. The jacket must adapt to her body, not the body to the jacket.
