PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a heavyweight cotton fleece or cotton-poly blend hoodie. It has a matte finish with high light absorption (low specularity). The material is thick, meaning folds should be soft and voluminous rather than sharp creases. The inner hood lining is a contrasting heather grey jersey fabric. - **Key Features:** - **Zipper:** Central metal zipper with black tape. - **Ribbing:** Elasticated ribbed cuffs at the wrists and a ribbed hem at the waistline. - **Hood Structure:** The hood has volume and a grey inner lining that must remain visible at the collar area. - **Drawstrings:** Currently held by the source model; these are flat, black, woven cords. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** - **Sleeves:** The user's bare arms must be fully encased. The fabric should bulk slightly around the deltoids and biceps to reflect the user's muscular build, draping vertically from the widest point of the shoulder. - **Drawstring Correction:** **CRITICAL:** The source image shows the drawstring being held horizontally. In the simulation, the drawstrings must be detached from that vector and simulated to hang vertically due to gravity, resting against the chest. - **Torso:** The garment is a relaxed fit. It should hang relatively straight from the pectorals, minimizing waist tapering. - **Occlusion Handling:** - **Necklace:** The user's silver pendant necklace sits low. Depending on the zipper height, the necklace should either be occluded by the fabric or tucked inside the neck opening. It must NOT float on top of the zipper. - **Beard/Jaw:** The hoodie collar/neckline must sit *behind* the user's beard. The beard hair must layer over the top of the garment's neck seam. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user is in a low-light, outdoor night setting with overhead, slightly diffuse artificial lighting. - The bright, flat studio lighting of the source garment must be darkened significantly. - Shadows must be cast downwards (under the pectoral chest folds and inside the hood opening). - The black fabric must absorb the ambient noise/grain of the target photo to match the low-light quality. - **Color Calibration:** The neutral black of the hoodie must be color-graded to accept the warm, yellowish tint of the ambient street/patio lighting. It should appear as a dark, warm charcoal rather than a stark studio black. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The entire head, including the specific hairstyle, facial hair (beard texture), and skin tone of the face and neck, must remain frozen. The boundary line is strictly at the base of the neck. - **Body Integrity:** The user has a broad, muscular build. The simulation is strictly forbidden from narrowing the shoulders or slimming the arms. The hoodie must look filled out by the user's actual physical dimensions.
