PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment appears to be a cotton or cotton-blend Kurta. It possesses a matte finish with low light reflectivity (diffuse reflection only). The simulation must treat the material as semi-structured; it will hold a straight vertical line due to gravity but will crease sharply rather than ripple fluidly at bend points (like the elbows). - **Key Features:** The repeating red and gold leaf motif pattern must remain crisp and undistorted. The V-notch neckline with the button/loop detail is critical. The 3/4 sleeve length must be respected (exposing the user's forearms/wrists unlike their current long sleeves). The side slits and straight hemline characteristic of a Kurta must be preserved. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The Kurta is a tunic style, meaning it will extend below the waist, covering the hips and the top portion of the light blue jeans. On the user's right arm (holding the phone), the fabric must bunch and compress at the inner elbow due to the flexion. On the left side, the garment should hang straight with a slight drape outward over the hip. The sleeves should end at the mid-forearm. - **Occlusion Handling:** This is a high-complexity occlusion scenario. The **Right Hand and Smartphone** are positioned directly center-mass; the new garment must be rendered exclusively *behind* these elements. The user's loose hair falls over both shoulders; the garment texture must be generated underneath the hair layers. The handbag strap on the left hand does not interfere with the torso but creates a spatial boundary for the left sleeve. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user is in a retail environment with multiple overhead cool-white LED downlights. This creates a flat, evenly lit foreground with soft shadows casting downwards. The source image has warm, directional studio lighting. The rendered Kurta must be color-graded to remove the warm studio cast and adopt a cooler, slightly desaturated tone to match the retail ambiance. - **Color Calibration:** The grey base of the Kurta needs to respond to the ambient retail light. Shadows on the garment (specifically under the bust and at the elbow folds) must match the density and softness of the shadows seen on the user's current jeans. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's visible facial features, jawline, and the specific volume/fall of her hair must remain completely frozen. The skin tone on the exposed neck and the newly exposed forearms (due to shorter sleeves) must match the user's original skin tone exactly. - **Body Integrity:** The user's body shape (shoulder width, bust size, and hip width) must be preserved. Do not morph the user's physique to match the slimmer silhouette of the model in the source image. The simulation must fit the cloth to the user, not the user to the cloth.
