PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a cotton jersey blend tank top. It possesses high pliability and low bending stiffness, unlike the user's current structured button-down. The texture should appear matte and soft, absorbing ambient light rather than reflecting it specularly. The white piping (binding) at the neck and armholes is slightly thicker and stiffer than the main body fabric. - **Key Features:** The central graphic ("NORTH CAROLINA" arch, number "88", and stars) with its distressed/vintage print texture must be preserved without distortion. The contrasting white ribbed binding on the neckline and armholes is the defining boundary feature. The bottom hem is a standard double-stitch and should not flare excessively. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Unlike the current stiff collared shirt, the tank top must drape closer to the torso following the contours of the pectorals and abdomen. The garment is sleeveless; therefore, the simulation must reconstruct the user's upper arms and shoulders (currently covered by black sleeves) with accurate skin texture and anatomical volume. The neckline is a scoop neck, sitting significantly lower than the current shirt collar, exposing the clavicle area. - **Occlusion Handling:** The user's **Left Hand** is raised and interacting with the center chest area. The simulation must render the tank top fabric *beneath* this hand. If the hand placement coincides with the tank top's lower neckline, the fingers may impinge on bare skin rather than fabric. The **Right Hand** is in the pocket; the hem of the tank top should naturally bunch slightly or curve around the wrist insertion point at the hip. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user is standing in a room with diffuse, omnidirectional lighting (likely overhead fluorescent mixed with daylight), resulting in soft, low-contrast shadows. The red tank top must not have harsh highlights. Shadows cast by the left hand onto the chest/garment must be soft and consistent with the ambient occlusion seen under the user's chin. - **Color Calibration:** The source red is vibrant. It must be slightly desaturated or modulated to match the neutral/cool white balance of the room to prevent it from looking like a pasted sticker. The white binding on the shirt must match the white temperature of the user's trousers (slightly warm off-white). PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's entire head region—specifically the beard line, hair volume, jaw structure, and facial expression—must be absolutely frozen. - **Body Integrity:** The user's torso width and shoulder slope must remain unchanged. Do not artificially bulk the subject's muscles despite the athletic nature of the garment. Crucially, the skin tone generated for the newly exposed arms and shoulders must be a seamless colorimetric match to the user's existing face and neck skin tone.
