PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment is a black cotton-jersey blend. It possesses a matte finish with high light absorption and low reflectivity. The simulation must treat this as a soft-body material with moderate elasticity (stretch) and standard drape weight—it will not hold rigid shapes like denim nor flow as fluidly as silk. - **Key Features:** The distinct scoop neckline and the width of the shoulder straps (significantly wider than the user's current spaghetti straps) are critical. The hemline is straight with side stitching. The texture must remain smooth and uniform, devoid of sheen. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** Due to the user's "hands-on-hips" pose, the fabric must exhibit slight tension across the chest and bunching/folding near the lower waist where the torso compresses. The silhouette must change drastically: the simulation must remove the volume of the current "peplum/puffed" top and replace it with the straighter, closer-to-body fit of the tank top. The garment must follow the natural curve of the waist into the hips, stopping where the white bottoms begin. - **Occlusion Handling:** 1. **Hair:** The user's long dark hair falls over both shoulders and down the back. This hair must be segmented and layered *over* the new black tank top. (Note: Precise segmentation is required here as dark hair over a black top lowers contrast). 2. **Necklace:** The gold chain and green pendant must sit *over* the fabric if the new neckline rises high enough to touch it, or remain undisturbed on the skin. 3. **Arms:** The inner elbows and wrists near the waist must occlude the garment's side seams. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The User Image features strong, warm, directional sunlight coming from the left (user's right), creating soft shadows on the right. The black tank top must not be rendered as "absolute black"; it must accept warm, orange/red bounce light from the terracotta walls and the sun. Highlights on the black fabric should be warm-toned, not white/grey. - **Color Calibration:** The source garment is cool/neutral studio black. It requires a temperature shift to match the "golden hour" ambient occlusion of the target scene. The black levels must be lifted slightly to blend with the outdoor atmospheric perspective. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user's entire head (from chin upwards), neck structure, and hairstyle must be frozen pixel-perfect. - **Body Integrity:** The user's arm thickness and shoulder width must remain unaltered. While the clothing silhouette changes from flared to straight, the underlying waist and hip geometry must be inferred naturally from the visible shorts, strictly forbidding any slimming or warping of the user's actual torso volume.
