PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is black denim (cotton twill). Unlike the user's current soft, flowy fabric, this material is rigid and structural (approx. 12-14oz weight). It creates angular folds rather than fluid drapes. The texture must exhibit a matte finish with low-gloss specular highlights specifically on the seam ridges and stitching, simulating the characteristic friction of denim. - **Key Features:** The spread collar, central metallic button placket (silver/pewter finish), horizontal chest yoke seams, and vertical panel stitching must be preserved with high fidelity. The cuff structure and the slightly cropped, boxy hemline are essential to the silhouette. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The jacket must replace the volume of the current bell sleeves with a straighter, structured sleeve profile. Due to the user's clasped hands, the jacket's lower hem will interact with the wrists; the fabric must not "flow" through the hands but rather break or bunch slightly above them if the length dictates, or pass behind them. The shoulder line must remain sharp and structured, ignoring the soft slope of the current garment. - **Occlusion Handling:** 1. **Hair:** The long dark hair cascading over the user's right shoulder (viewer's left) and chest is a critical occlusion layer. It must be masked and composited *over* the right collar and chest panel of the denim jacket. 2. **Hands:** The user's clasped hands obscure the lower abdomen. The jacket simulation must terminate or be masked behind the hands and fingers to maintain depth perception. 3. **Necklace:** The gold chain sits high on the neck; depending on the jacket's collar openness, it should either be overlaid or naturally obscured by the denim collar. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user's environment has soft, diffuse indoor lighting, likely coming from a ceiling source, casting soft shadows downwards. There is a warm/yellow tint to the room and a potential pink color bleed from the curtain on the left. The studio-lit, cool-toned denim must be color-graded to match this warmer ambient temperature. Shadows within the jacket folds must be softened to match the room's lower contrast ratio. - **Color Calibration:** The black values of the denim must be lifted slightly to match the dynamic range of the user's photo. A subtle warm overlay should be applied to the jacket's highlights to reflect the room's off-white walls and wooden door, preventing the jacket from looking like a "cut-out." PHASE 4: IDENTITY PROTECTION - **Facial Lock:** Absolute freeze on the facial region from the chin up, extending to the ears. The hairline and the specific volume of the hair on the head must remain untouched. - **Body Integrity:** The user's shoulder width and torso volume must dictate the jacket size. Do not slim the waist or arms to match the source model's physique. The jacket must look like it is worn *by* the user, not pasted *onto* the user.
