PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a high-GSM cotton-blend fleece hoodie. It possesses a heavy, dense drape with low elasticity. The surface is matte and light-absorbent, unlike the user's current smooth, reflective tank top. The texture must convey thickness/volume, not clinging like a thin synthetic. - **Key Features:** The central metal zipper (high specularity) must remain straight but follow the torso's curvature. Ribbed elastic cuffs and bottom hemline are critical structural elements. The hood structure around the neckline and the drawstrings must be preserved. The kangaroo/side pockets add volume to the lower abdomen area. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** This is a significant geometry change from a sleeveless crop top to a long-sleeved, full-length garment. The hoodie must extend past the user's current waistline, covering the exposed midriff and overlapping the waistband of the beige joggers. The sleeves must generate cylindrical volume around the user's bare arms, with natural fabric bunching at the wrists (stacking) due to the ribbed cuffs. The shoulder line will rise slightly due to the padding of the hood material. - **Occlusion Handling:** 1. **Hair:** The user's voluminous, shoulder-length curly hair is a major occlusion layer. The hoodie's collar and hood area must be composited *behind* the hair strands. 2. **Hands:** The user's left hand (viewer's right) rests on the hip/waistband. The hoodie sleeve must terminate at the wrist, ensuring the hand remains the top layer. 3. **Waistband:** The bottom hem of the hoodie will likely obscure the drawstring details of the user's current joggers. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user is illuminated by soft, diffuse studio lighting, slightly front-right based on facial highlights. The navy blue hoodie must be rendered with soft, non-harsh shadows. Deep ambient occlusion is required in the underarm areas and inside the hood cavity to ground the garment. - **Color Calibration:** The user image has a slightly warm/rosy tint. The source hoodie is cooler. Apply a subtle warm curve adjustment to the navy blue fabric to match the white balance of the user's environment, ensuring the dark blue does not look "pasted on" or artificially saturated. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's entire head, including the specific curl pattern of the hair, jawline, and neck (above the clavicle), must be frozen and masked out of the generation. - **Body Integrity:** Do not warp the user's shoulder width or arm length. While the hoodie adds volume, the underlying skeletal structure must remain consistent. Do not slim the user's hips where the hoodie covers them; maintain the wide-leg silhouette of the original trousers below the hoodie hem.
