PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment appears to be a textured crinkle cotton or linen blend. It has a matte finish with low reflectivity but high surface texture detail. The material possesses medium stiffness—enough to hold the shape of the puff sleeves and the peplum structure, but soft enough to drape vertically along the pleats. - **Key Features:** The V-neckline with delicate crochet/lace trim must be preserved. The vertical row of fabric-covered buttons on the bodice is essential. The distinct empire-waist seam (where the bodice meets the flared bottom) and the "puff" architecture of the sleeves with their specific cuff detailing must be retained. The vertical "crinkle" texture of the weave is a defining characteristic. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The user is leaning against a railing with the right hip cocked slightly. The garment must follow this torso curvature. The right shoulder is elevated due to the arm resting on the railing; the right puff sleeve must compress slightly at the underarm and sit higher on the shoulder. The peplum flare (bottom of the shirt) should drape naturally over the upper hips, widening slightly, rather than clinging tight like the current red top. - **Occlusion Handling:** The user's hands are clasped at the lower waist/pelvis. The hem of the new top will likely interact here; the hands and the prominent red/gold bangles (chooda) must be segmented as the foreground layer, ensuring the shirt fabric flows *behind* or stops *above* the hands/wrists, never covering them. The gold necklace must be layered *over* the new V-neck skin exposure. The green railing bars crossing the lower torso area must remain in the foreground if the shirt hem hangs low enough to intersect them. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target environment features soft, diffuse outdoor lighting (dusk/overcast) with cool, bluish undertones. The source garment has warm, beige studio lighting. The rendered shirt must shed its warm yellow cast and adopt a cooler, neutral white tone to match the ambient outdoor light. Shadows should be soft and contact-based (ambient occlusion) rather than hard directional shadows. - **Color Calibration:** The white point of the shirt needs to match the white of the balcony floor tiles or the railing. Desaturate the cream/beige tints from the original studio photo to prevent the shirt from looking "dirty" or yellowed against the cool outdoor backdrop. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** Absolute freeze on the facial region including the bindi, nose ring, eyebrows, and hairline. The long hair draping behind the shoulders must remain untouched. - **Body Integrity:** Strict prohibition on warping or slimming the user's waist or arms. The volume of the user's arms must be filled with their original skin tone, not the source model's. The silhouette of the black trousers below the shirt line must remain exactly as is to maintain the user's stance.
