PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a thick, cotton-blend fleece or jersey material typical of hoodies. It possesses high structural integrity (stiffness) compared to the user's current thin tank top. It has a matte finish with zero specular highlights; light should diffuse softly across the surface rather than reflect sharply. - **Key Features:** - **Pattern:** The all-over white floral print on the red base must remain geometrically consistent and not distort excessively during warping. - **Hardware:** The white flat drawstrings at the neck are a critical anchor point. - **Cuffs/Hem:** The ribbed texture on the wrist cuffs and bottom hemline creates a distinct silhouette change from the current straight hem. - **Volume:** The hood mass gathering at the back of the neck needs to be simulated, adding bulk behind the user's hair. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** - **Sleeve Generation:** The target user is currently sleeveless. The simulation must generate full-length sleeves that follow the cylindrical volume of the arms. The fabric should stack slightly (accordion folds) at the elbows and wrists due to the fabric thickness, rather than clinging tight like skin. - **Torso Fit:** The hoodie is a relaxed fit. It must sit away from the waist, eliminating the current "hourglass" contour visible in the tank top. The hemline should drop below the user's navel, covering the exposed midriff and overlapping the waistband of the beige trousers. - **Occlusion Handling:** - **Hair:** The user's voluminous, dark curly hair falls significantly over the shoulders. This needs pixel-perfect segmentation; the red hoodie must be rendered *behind* these curls, not pasted over them. - **Hands/Wrists:** The user’s left hand rests near the thigh. The hoodie cuff must terminate naturally at the wrist bone, ensuring the hand remains the top-most layer. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target image utilizes soft, high-key studio lighting (neutral white) with a light source likely from the front-left. The source hoodie has warm, yellowish "mall lighting" reflections. These yellow casts must be neutralized. Shadows on the hoodie must be soft and diffuse, generated in the folds of the arms and under the bust, matching the ambient occlusion of the studio shot. - **Color Calibration:** The red of the hoodie must be color-corrected to remove the indoor tungsten tint, shifting it towards a true, cooler red to match the white balance of the target environment. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's face, neck skin texture, and specific jawline definition must be frozen. The simulation stops strictly at the base of the neck. - **Body Integrity:** Do not slim the user's arms or torso. The simulation must add additive volume (thickness of the fleece) to the user's silhouette, not subtract from it. The user's shoulder width and hip placement must remain anatomically exact.
