PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a heavy-weight cotton/fleece blend hoodie. It possesses high structural integrity with low elasticity compared to the user's current lace top. It has a matte finish that absorbs light rather than reflecting it. Simulation must account for thick fold volume, specifically preventing the "shrink-wrap" effect common with thinner fabrics. - **Key Features:** 1. The white cursive "Tokyo" text across the chest (must undergo geometric warping to match the torso angle but remain legible). 2. Two long drawstrings (must react to gravity based on the user's seated forward lean). 3. Thick ribbed cuffs at the wrists and a ribbed hemline at the waist. 4. The bulk of the hood visible around the neck area. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Due to the user's seated, cross-legged pose, the hoodie behavior must change significantly from the source image: 1. **Abdominal Bunching:** The lower hem will not hang straight; it must pool and fold horizontally across the midsection where the torso meets the legs. 2. **Shoulder Drop:** The shoulder seams must drape lower than the natural shoulder line (drop-shoulder fit). 3. **Sleeve Compression:** Significant fabric bunching is required at the inner elbows due to the bent-arm posture. - **Occlusion Handling:** 1. **Hands:** The user's clasped hands resting on the lap are the primary occlusion layer. The hoodie must be masked *behind* the hands and wrists. 2. **Hair:** The user's hair flows behind the shoulders; the hoodie's collar/hood geometry must be generated around the neck without clipping through the jawline, while maintaining the hair's current visibility if it overlaps the shoulder line. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user environment features diffuse, overhead indoor lighting (likely fluorescent/LED) creating soft shadows. The source garment's lighting is cooler. The hoodie render must adopt the warm ambient occlusion of the bedroom. Shadows must be generated under the bust, inside the hood cavity, and deep within the abdominal folds. - **Color Calibration:** The dark forest green of the hoodie must be color-graded to match the white balance of the user image. The white text must not be pure #FFFFFF; it requires a slight tinting to match the room's ambient light temperature to blend realistically. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** Absolute pixel preservation of the user's face (eyes, nose, mouth, smile lines), neck, and ear structure. The facial region is a strict "No-Modify" zone. - **Body Integrity:** Zero mesh warping of the user's underlying anatomy. The simulation must add volumetric bulk to the user (as a hoodie is thicker than the current lace top). Do not slim the arms or waist; the silhouette should expand slightly to reflect the heavy fabric thickness.
