PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a cotton-blend jersey or fleece (sweatshirt material). It has a matte finish with high light absorption and low reflectivity. The simulation must account for significant fabric weight and thickness; it should not cling like the current spandex top but rather hold its own volume, creating softer, larger folds rather than sharp wrinkles. - **Key Features:** - **Pattern Continuity:** The white all-over floral print must remain consistent across seams. - **Structural Elements:** The hood structure (falling back behind the neck), white drawstrings at the collar, ribbed elastic cuffs at the wrists, and the ribbed hemline at the waist. - **Silhouette:** This is a long-sleeved, relaxed-fit garment, distinct from the user's current sleeveless fitted top. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** - **Left Arm (Raised):** Gravity will cause the sleeve to slide down towards the shoulder/axilla. The fabric must bunch significantly at the armpit and shoulder junction, exposing the wrist. - **Right Arm (On Hip):** The sleeve must compress at the elbow interior and wrist, creating transverse folds. The fabric tension should pull slightly across the chest towards this raised elbow. - **Torso:** The hoodie fits looser than the current purple top. It should drape vertically from the chest, bridging the gap between the bust and the waist rather than hugging the skin. The hemline should sit near the upper hip, interacting with the denim shorts. - **Occlusion Handling:** - **Hair:** The user's long black hair flows over her right shoulder and right breast. This is a critical occlusion layer; the hair must be segmented and composited *over* the new red hoodie, with shadow interaction where the hair rests on the thick fabric. - **Hands:** The right hand resting on the thigh must remain visible. If the hoodie length covers the wrist, the cuff must terminate before the hand or drape naturally over the wrist bone. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user is in a bright indoor environment with overhead lighting (cool to neutral white), casting soft shadows downward and slightly to the right. The new garment must shed the warm, yellow-tinted ambient light of the mall (source image) and adopt the flatter, cleaner lighting of the user's room. - **Color Calibration:** The source red is likely skewed warm due to mall lighting. It requires desaturation and white-balance correction to appear as a "true red" against the user's white wall background. Shadows within the hoodie folds must match the contrast levels of the shadows on the user's shorts. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's face (specifically the "pout" expression), eyes, makeup, and jawline must remain completely frozen and pixel-perfect. - **Body Integrity:** The legs, exposed skin on the thighs, and general posture must remain untouched. While the hoodie will add visual bulk to the upper body due to fabric thickness, the underlying skeletal structure and hip width must not be warped or slimmed.
