PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment appears to be a structured raw silk or silk-blend with padding. Unlike the current soft ribbed knit, this material is rigid and non-elastic. It must render with a semi-matte sheen that catches light on the curves of the bust, while the sequins at the hem must react with high specular reflectivity. - **Key Features:** The deep V-neckline with multi-colored triangular mirror work and the heavy silver/gold sequined waistband are critical fiducials. The pre-molded cup shape must be preserved to maintain the garment's structured look, rather than flattening it against the body. The dangling tie-back strings (dori) should be simulated draping over the shoulder or removed if they clutter the composition. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** This is a drastic silhouette change from a long-sleeve high-neck top to a sleeveless deep-neck blouse. The simulation must generate realistic skin texture for the user's currently covered arms, shoulders, and upper chest (décolletage). The blouse is a "choli" cut, meaning it fits tightly to the torso and ends at the mid-waist; it should not tuck in but sit structurally just above the hips/pants line. - **Occlusion Handling:** **CRITICAL:** The user has long, dense black hair falling over both shoulders and the chest. This hair must be masked precisely and layered *over* the new garment. The fabric cannot sit on top of the hair. Additionally, the user's right hand and the lime-green phone occupy the lower torso region; the sequined hem of the blouse must pass behind the hand/phone or stop just above it, strictly respecting the depth layer of the hand. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The user is in a room with soft, diffuse overhead lighting that casts a slight shadow to her right (viewer's right). The new garment's texture maps (normal and specular) must align with this top-down/left-bias light source. The sequins should reflect the ambient warm-white room tone, not the cool white of the flat-lay photo. - **Color Calibration:** The User Image has a slightly warm, low-contrast indoor cast. The Cloth Image is high-contrast and neutral. The beige/gold tone of the blouse must be warmed slightly (color grading) to blend with the skin tone and room atmosphere, preventing it from looking "pasted on." PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's face, specifically the jawline, lips, nose, eyes, and the specific fringe/bangs of the hairstyle, must be frozen and untouched. - **Body Integrity:** Strictly forbidden to alter the user's seated posture or body volume. The generated arms must match the volume implied by the current sleeves and the skin tone of the face/hands. Do not slim the waistline to fit the mannequin shape of the source cloth.
