PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a heavy-weight cotton-blend fleece or French terry. It possesses high structural integrity and stiffness compared to the user's current lightweight blouse. It acts as a matte surface with low specularity, absorbing light rather than reflecting it, though the rubberized graphic prints (stars, text) will have slightly higher reflectivity. - **Key Features:** - The central zipper mechanism and the hood bunching around the neckline. - The "MOTORSPORT" chest graphic, stars on the lower torso, and "RACING TEAM" text on the sleeves. - Dropped shoulder seams (oversized fit structure). - Elastic ribbed cuffs and thick ribbed bottom hem. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The garment must transition from the source's "model pose" to the user's side-angled stance. Unlike the current fitted top, the hoodie is oversized; it must hang loosely over the torso, creating a gap between the fabric and the user's waist. The sleeves must be generated to cover the user's currently bare arms, simulating heavy fabric folding at the elbow joint and bunching near the wrist. The hemline should fall lower than the current top, resting on the upper hip area. - **Occlusion Handling:** - **Hair:** The user's long, wavy hair currently cascades over her shoulders and chest. This hair layer must be masked and composited *over* the new hoodie to maintain realism. - **Left Hand/Pocket:** The user's left hand is tucked into her trouser pocket. The hoodie's left sleeve must terminate naturally at the wrist or bunch slightly above the pocket entry, ensuring the hand and the pocket interaction remain visible and are not covered by the sleeve. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user is in a room with soft, diffused ambient lighting, likely coming from the front-left, casting a soft shadow on the wall behind her to the right. The navy blue hoodie must be rendered with this soft, directional fall-off. The stark studio brightness of the source image must be dimmed to match the indoor exposure. - **Color Calibration:** The source image has a slight purple color cast from the background. Desaturate the white graphics on the hoodie slightly to match the neutral/warm tones of the user's room. The navy blue should appear deep and rich, not washed out, adhering to the contrast levels of the user's white trousers. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** Absolute freeze on the facial region (eyes, nose, mouth, chin) and the neck structure. The hairline must remain untouched. - **Body Integrity:** Strictly prohibit any warping or slimming of the user's waist or hips to match the source model's physique. The white trousers must remain exactly as they are, preserving the user's lower body stance and volume.
