PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a heavyweight cotton-fleece blend (jersey knit). It possesses high bending stiffness and internal friction, meaning it will create thick, tubular folds rather than fine, sharp creases. Surface reflection should be matte with high light absorption (low specularity), characteristic of soft cotton. - **Key Features:** The structural volume of the hood and collar area is critical. The thick white rope drawstrings, the front kangaroo pocket, the drop-shoulder seams, and the elasticized ribbed cuffs and bottom hem must be preserved. The garment's oversized silhouette is a defining design trait and must not be retargeted as a slim fit. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Due to the user's seated side-profile pose, the hoodie must exhibit "lap pooling." The fabric will bunch significantly at the abdomen where the torso compresses. The back of the hoodie should not cling to the spine but rather bridge the gap between shoulders and hips, smoothing out the back curve. The sleeves must exhibit heavy volumetric compression at the bent elbow inside the elbow pit. The hood itself should rest heavily against the upper back/neck area, adding silhouette bulk. - **Occlusion Handling:** 1. **Hair:** The user's long, dark hair covering the upper back and shoulder is the primary occlusion layer; the hoodie texture must render *underneath* the hair strands. 2. **Bag & Hands:** The patterned bag resting on the lap and the user's hands interacting with it are foreground elements. The bottom hem and lower kangaroo pocket of the hoodie must be masked *behind* these elements to maintain depth consistency. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user is in a natural outdoor environment with soft, diffuse daylight coming primarily from the upper left and rear (backlit/side-lit scenario). The studio lighting of the source hoodie (flat, bright indoor light) must be replaced with global illumination that casts soft shadows on the front of the torso and deeper occlusion shadows in the folds near the lap and under the arm. - **Color Calibration:** The source pink is vibrant; it requires slight desaturation and a shift toward a cooler tone to match the white balance of the outdoor scenery (bluish daylight). The brightness must be lowered to account for the lack of direct frontal sunlight in the user's shaded position. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's side profile (jawline, cheek, visible ear area) and the specific volume and flow of the long hair must remain pixel-perfectly frozen. - **Body Integrity:** Strict prohibition on warping the user's underlying geometry. The legs (jeans) and hip placement must remain untouched. The hoodie adds volume on top of the body; it must not be warped to make the user appear thinner. The natural "slouch" of the seated posture must be maintained.
