PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment appears to be a medium-weight Cotton or Cotton-Silk blend. It exhibits a matte finish with diffuse light scattering (no high gloss). The drape structure is semi-rigid; it holds vertical crease lines well but flows moderately. It is not elastic. - **Key Features:** The distinctive large-scale leaf print (magenta base with pastel pink and grey overlays) must remain undistorted. The "V-notch" neckline stands up slightly and must not lay completely flat against the skin. The sleeve length is roughly 3/4 (mid-forearm); the straight hemline at the bottom and side slits (if visible in generation) are critical structural elements. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The user is in a relaxed standing pose with a slight hip tilt. The new garment is a long Kurta (longer than the user's current white tunic). The simulation must extend past the hips, draping straight down due to gravity, effectively masking the upper thigh portion of the black trousers. The fabric should relax around the shoulders but maintain the structured straight cut of the Kurta, avoiding the flared/A-line silhouette of the user's original white top. - **Occlusion Handling:** The user's dark, shoulder-length hair is the primary occlusion layer; it must be segmented and composited *over* the new magenta fabric on both shoulders. The watch on the user's left wrist is a hard collision object; the sleeve must either terminate before the watch or sit naturally underneath it, ensuring the watch remains visible. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target environment features warm, overhead artificial lighting (tungsten/yellow hue) with multiple point sources (reflected in the elevator). The source garment (currently lit by cool/neutral daylight) must be color-graded to absorb this warm ambient temperature. Shadows must be cast downward from the bust and collarbone areas to match the room's overhead light direction. - **Color Calibration:** The magenta of the kurta will shift towards a warmer, slightly deeper berry tone due to the yellow ambient light of the hotel lobby. Contrast must be increased slightly to match the dynamic range of the user's photo. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's entire head, facial expression, neck skin tone, and hair structure are strictly frozen. The hands and the visible portion of the lower legs/feet must remain pixel-perfect. - **Body Integrity:** Strictly forbidden to warp or slim the user's torso or arm width to match the source model. The simulation must wrap the source cloth around the *user's* existing volumetric data. Preserves the user's shoulder width and hip alignment.
