PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a quilted cotton material with internal batting. It possesses significant structural rigidity and "loft" (thickness). Unlike the user's current smocked top, this fabric will not cling to the body contours. It must exhibit a matte finish with low specular highlights, but the quilted stitching lines must create micro-shadows (relief texture) to convey depth. - **Key Features:** The Mandarin/stand collar is a critical structural element that must stand upright around the neck. The pink buttons, patch pockets near the hem, and specifically the contrasting blue-and-white patterned cuffs must be preserved. The tiger print pattern must wrap continuously around the volumetric shape of the torso and arms, adhering to the quilted topography. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Due to the quilted nature, the jacket must sit with a "boxy" fit, adding volume to the user's silhouette rather than following the waistline curve of the current tube top. - **Shoulders:** The jacket shoulders must extend slightly past the user's natural shoulder line to simulate padding/thickness. - **Right Arm:** Because the user's right arm is bent at the elbow (hand on hip), the thick fabric must simulate heavy compression wrinkles at the inner elbow and tension across the outer elbow. The cuff must align with the wrist, interacting with the large bracelet. - **Occlusion Handling:** - **Hair:** The user's long, wavy brown hair falling over the right shoulder and chest is a primary occlusion layer. A high-precision segmentation mask must be applied to layer this hair *over* the new jacket. - **Necklace:** The large silver choker sits high. The jacket's mandarin collar will likely rise to the same level. Physics simulation must decide if the collar covers the necklace or if the jacket is worn slightly open; ideally, the jacket collar wraps *around* or sits just below the chin, potentially obscuring the lower part of the necklace. - **Right Hand:** The right hand resting on the hip must mask out the jacket hemline. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user image features soft, warm, diffused lighting, likely from the front-left, casting soft shadows against a textured beige wall. The jacket (originally photographed in flat, cool studio light) must be color-graded to accept this warm ambient light. - **Color Calibration:** The bright pink of the jacket must be slightly desaturated and shifted towards yellow/orange to match the warm color temperature of the target scene. Shadows cast by the hair onto the jacket and by the jacket onto the jeans must match the density and softness of the existing shadows in the user image. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's facial structure, skin tone, make-up, and the specific tattoo on the left upper chest (if visible near the collar) must be frozen. However, since the jacket covers the shoulders, the tattoo will likely be covered. - **Body Integrity:** The simulation must strictly prohibit slimming the user's figure to fit the jacket. The user's waist width and arm thickness must remain constant, with the jacket adding the appropriate bulk on top of the existing physiological frame. The hands and fingers must remain unaltered.
