PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a medium-wash denim jacket. The simulation must replicate rigid, heavy-weight cotton twill physics. Unlike the user's current satin/spandex top, this fabric does not cling; it holds its own structure. Light reflection should be matte with low specularity, except for slight highlights on the metallic buttons and the white embroidery. - **Key Features:** The large white lace/embroidered butterfly on the left chest is the primary focal point and must be preserved without distortion. Silver buttons, collar stiffness, and the vertical seam lines on the front panels must be retained. The "open-front" nature of the source image needs to be resolved (either zipped/buttoned or rendered open revealing a base layer, depending on standard VTO protocol, usually rendered closed or semi-open). PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** - **Shoulders & Torso:** The jacket must sit wider on the shoulders than the current halter top, adding structural bulk. It should drape straight down from the bust rather than cinching at the waist. - **Left Arm (Raised):** Due to the user touching her hair/face, the rigid denim sleeve must demonstrate significant bunching and creasing at the inner elbow (compression folds). The cuff should retract slightly down the forearm. - **Right Arm (Down):** This sleeve should hang with tubular volume, maintaining the stiff shape of a denim sleeve, not collapsing against the skin. - **Occlusion Handling:** - **Hair:** The user has long, thick hair cascading over the left shoulder and back. The jacket collar and shoulders must generate *under* this hair layer. - **Hand:** The user's left hand is near her face/hair. If the sleeve extends to the wrist, the cuff must be properly layered behind the hand interaction. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user environment is an outdoor evening setting with warm, diffused artificial light (from the "SEVEN OAKS" sign and string lights). The source image is cool, bright studio lighting. The denim texture must be darkened significantly to match the low-light exposure. The lighting direction is soft and ambient; harsh studio highlights on the denim must be flattened. - **Color Calibration:** The bright blue of the denim must be color-graded to accept the warm (amber/orange) cast of the background lights. The white butterfly embroidery should not appear stark white but should reflect the warm ambient glow of the venue to integrate realistically. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's side profile, jawline, ear, and the specific gesture of the hand touching the face must remain pixel-perfectly frozen. - **Body Integrity:** Strictly forbidden to slim the user's arms or torso. The simulation must add the volume of the jacket *on top* of the user's natural measurements. The waistline of the jeans (visible at the bottom of the current top) should interact naturally with the jacket's hem (likely covering the top of the jeans).
