PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a heavyweight cotton-fleece blend hoodie. It has a matte finish with low specular reflection but high light diffusion. The simulation must account for significant thickness (gsm > 300), resulting in soft, rounded folds rather than sharp creases. The material is stiff enough to hold volume away from the body, particularly at the hood and sleeves. - **Key Features:** The central "Wednesday Addams" graphic illustration and the text "WE DON'T HUG" are critical; they must warp realistically around the chest curvature. The ribbed elastic texture on the cuffs and bottom hem, the drawstrings at the neck, and the volume of the hood bunched around the collar area must be preserved and rendered accurately. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** - **Right Arm (Raised):** Due to gravity, the heavy sleeve fabric will slide down towards the shoulder, creating deep transverse folds (accordion-style bunching) at the armpit and shoulder joint. The cuff should settle lower on the forearm, exposing the wrist. - **Left Arm (Relaxed):** The sleeve will hang straight with slight "stacking" (bunching) above the wrist cuff, as hoodie sleeves are typically longer than the arm span. - **Torso:** Unlike the current form-fitting top, the hoodie must hang loosely. It should bridge the gap between the bust and hips without clinging to the waist, puffing out slightly above the bottom ribbed hem. The hood bulk will sit behind the neck, elevating the silhouette at the trapezius. - **Occlusion Handling:** The user's long dark hair is the primary occlusion layer. The hair currently draping over the shoulders must be segmented and re-layered *on top* of the new hoodie fabric. The right hand resting on the head is clear of the garment, but the wrist intersection with the new sleeve cuff requires precise masking. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target environment features strong, directional sunlight coming from the upper-left (viewer's perspective), creating hard shadows. The hoodie must be relit to show bright highlights on the left shoulder and chest, with deep, high-contrast shadows under the right armpit, inside the hood folds, and under the bust. - **Color Calibration:** The source cloth image has cool/interior lighting. The pink/beige tone of the hoodie must be color-graded to interact with the warm, golden-hued sunlight of the target scene. This involves shifting the white point towards yellow/orange to integrate it into the industrial outdoor setting. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's facial features (eyes, nose, mouth), jawline, and skin tone on the face and hands must remain strictly frozen. The hair geometry must generally remain consistent, only adjusting slightly where it interacts with the added bulk of the hood. - **Body Integrity:** The underlying skeletal structure must remain unchanged. Do not slim the user's torso to fit the source image dimensions; conversely, do not artificially slim the bulky hoodie to match the user's current thin silhouette. The final result must show the natural volumetric increase expected when wearing a thick sweatshirt.
