PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a fitted, jersey-knit cotton blend (likely cotton/spandex). It has a matte finish with low specular highlights. Unlike the user's current voluminous synthetic blouse, this fabric behaves with high elasticity, hugging the torso contour rather than draping loosely. It creates soft, shallow tension wrinkles rather than crisp folds. - **Key Features:** * **Graphics:** The white butterfly print on the center chest must be preserved without distortion. * **Cut:** Deep scoop neckline and sleeveless armholes (tank top style). * **Hemline:** Cropped length, ending slightly above the navel/natural waist. * **Color:** Deep Royal Blue base. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The simulation must transition from the user's current loose, off-shoulder silhouette to a skin-tight fit. The source garment must conform tightly to the bust and taper at the ribcage. * **Critical Synthesis:** The user is currently wearing long, puffy sleeves. The new garment is sleeveless. The simulation requires substantial **generative inpainting** to synthesize realistic bare skin on the user's arms and shoulders where the white fabric currently exists, matching the skin texture and tone of her neck. - **Occlusion Handling:** * **Hair:** The strands of hair falling over the user's left shoulder (viewer's right) and chest area are the primary occlusion. These must be segmented and layered *over* the new blue strap and upper chest area. * **Waistline:** The user's jeans waistband sits close to the crop line. Ideally, the top should end just above the jeans, allowing a small sliver of skin (midriff) if the geometry allows, or slightly overlapping the waistband if the fit is longer. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target environment is high-contrast neon/night lighting, completely different from the source's overcast daylight. * **Left Side (Viewer's Left):** Must reflect the red/orange neon glow from the background sign. The royal blue fabric should shift towards a purplish/dark magenta hue in these rim-light areas. * **Right Side (Viewer's Right):** Must reflect the cyan/blue neon light. The fabric here will appear vivid electric blue. * **Center:** Deep shadows in the torso folds. - **Color Calibration:** The flat, neutral lighting of the source image must be discarded. A heavy color grade is required to simulate "gelled" lighting. The white butterfly graphic must reflect the ambient colored light (tinting slightly pink/blue depending on position) rather than remaining stark white. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's entire head, including the specific tilt, jawline definition, and the way the neon light hits her cheekbones, must be frozen. - **Body Integrity:** Strict prohibition on body warping. The user's torso width and bust volume must remain consistent. The synthesis of the bare arms must align with the user's natural BMI and muscle tone, ensuring the generated limbs do not look thinner or smoother than the visible skin on her neck.
