PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a white "Schiffli" or eyelet cotton fabric. It possesses a matte finish with high-frequency texture due to the perforated embroidery. The physics engine must treat this as a semi-structured lightweight cotton—it should hold its shape at the seams but drape fluidly. It requires slight subsurface scattering simulation to account for light passing through the eyelet holes. - **Key Features:** - The specific V-neckline with pink/floral piping detail. - The complex sleeve cuffs (lace border -> floral panel -> lace edge) and the identical detailing on the bottom hem. - The bell-sleeve silhouette which flares slightly at the wrist. - The all-over perforated floral pattern of the fabric. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Unlike the current tucked-in/short shirt, the source Kurta is a long tunic. The simulation must drape the fabric *over* the hips and thighs, extending below the user's current waistline. The fabric should hang relatively straight due to gravity, with slight tension wrinkles across the chest due to the user's bust line. The bell sleeves must hang loose around the forearms, not clinging to the skin. - **Occlusion Handling:** - **Hair:** The user has long, dark hair cascading over both shoulders and the upper chest. This is a critical occlusion layer; the Kurta texture must generate *underneath* the hair strands. - **Hands/Wrists:** The user's hands are positioned near the hips/pockets. The long Kurta hem will likely intersect with this area. The simulation must render the fabric draping *around* the wrists and falling behind the hands if they are inside pockets, or bunching slightly if the hands are pressing against the side of the body. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user's environment has cool, diffuse overhead indoor lighting (LED typical). The source cloth image is warmer. The generated garment must be color-graded to reduce yellow warmth and align with the cooler white balance of the room. Shadows must cast downwards, accentuating the depth of the eyelet texture. - **Color Calibration:** The "white" of the kurta must match the dynamic range of the user's current white shirt to ensure it fits the scene's exposure levels. The floral colors (pinks/greens) needs to be desaturated slightly to match the slightly washed-out indoor lighting of the target image. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** Absolute freeze on the facial region from the chin up, including the specific jawline contour, makeup, and skin texture. - **Body Integrity:** The user's body volume, specifically shoulder width and arm circumference, must be preserved. The simulation must not slim the waist to fit the garment; rather, the garment must expand to fit the user's natural silhouette. No warping of the black pants where they remain visible below the new hemline.
