PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a lightweight floral bomber jacket, appearing to be composed of a soft woven viscose or polyester blend with moderate drape. It features a matte finish with low specularity. The collar, cuffs, and hem are ribbed elastic knit, which possesses higher stiffness and tensile strength compared to the body fabric. - **Key Features:** The high-contrast monochromatic tropical leaf pattern must be preserved without distortion. The silver center zipper (hard surface element) needs to maintain metallic reflectivity. The distinct black ribbed elastic bands at the neck, wrists, and waist are structural anchors that define the bomber silhouette. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Due to the user's "arms raised" pose (bilateral shoulder abduction), the jacket shoulders must elevate significantly. The fabric of the bodice will experience tension pulling upward from the waist hem. The sleeves must be generated to cover the currently bare arms; gravity will cause the fabric to slide down the forearms, resulting in significant bunching/stacking of the material at the elbows and upper arms rather than the wrists. The elastic waistband should settle near the natural waistline/high hip, replacing the current peplum flare. - **Occlusion Handling:** The user's long dark hair flows over the left shoulder and down the back; this hair mask must be segmented and layered *over* the new jacket collar and shoulder panel. The user's hands are behind the head; the distal ends of the jacket sleeves (cuffs) will interact with the wrists/forearms—ensure the bracelets are either realistically covered by the cuff or occlude the cuff if the sleeve slips down. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target scene utilizes soft, diffuse studio lighting, predominantly coming from the front-right. The new garment must render with soft ambient occlusion, particularly in the deep folds created by the lifted arms (axillary region) and the bunched sleeves. The black background of the fabric should not crush to absolute black but retain texture detail. - **Color Calibration:** The cream/off-white floral pattern on the source jacket must be color-graded slightly warmer to match the warm skin tones and ambient temperature of the user's environment, avoiding a stark, cool-white cutout look. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's entire head, including facial expression, jawline, and the specific hairline interaction with her hands, is to be frozen and masked from alteration. - **Body Integrity:** Strictly maintain the user's underlying skeletal structure and skin volume. Do not slim the torso or arms to match the flat-lay proportions of the jacket. The simulation must add the volumetric bulk of the bomber jacket on top of the user, making her silhouette naturally wider than with the current thin halter top.
