PHASE 1: VISUAL DECONSTRUCTION - **Fabric Physics:** The source garment appears to be a high-quality cotton or rayon blend with a matte finish. It exhibits low specularity (it does not shine under light) but has high flexibility. The simulation must treat the bodice as semi-structured while the sleeves and skirt area possess a fluid, gravity-dependent drape. - **Key Features:** The complex geometric and floral ethnic prints (white and red motifs on navy blue) must be preserved without distortion. Critical structural details include the round neckline, the distinct waistline seam where the pleats begin, and the specific border pattern on the sleeve cuffs. The gathered pleating at the waist is a defining feature that must remain visible. PHASE 2: FIT & DRAPE SIMULATION - **Body Mapping:** The user is standing with a slight weight shift. The garment's bodice must conform to the user's torso volume, adhering snugly at the bust and tapering at the natural waist. The left arm is bent at the elbow to hold a clutch; the fabric physics engine must generate tension wrinkles at the outer elbow and bunching (compression folds) at the inner elbow of the left sleeve. The right sleeve should hang straight with minor gravity-induced rippling. - **Occlusion Handling:** This is a high-complexity occlusion scenario. The user's long dark hair falls over both shoulders and down the right side of the chest; the new garment must be rendered logically *behind* these hair strands. Additionally, the user's left hand, the wrist accessories (red bangles), and the beige clutch bag must partially occlude the left sleeve cuff and lower waist area. PHASE 3: ENVIRONMENT & LIGHTING - **Light Match:** The target environment is a shopping mall with diffuse, high-intensity overhead LED lighting (cool to neutral temperature). The flat studio lighting of the source garment must be replaced with this multi-directional ambient light. Shadows should be soft and fall downwards, specifically casting small drop shadows under the bust and where the sleeves meet the torso. - **Color Calibration:** The source garment is deep navy blue. In the mall environment, the black point must be lifted slightly to match the contrast levels of the user's black trousers. The white patterns on the dress should reflect the slightly cool/blue tint of the mall lighting rather than pure studio white to ensure integration. PHASE 4: IDENTITY PROTECTION - **Facial Lock:** The user’s entire head region, specifically the jawline, chin, smile lines, and eyes, must remain strictly pixel-frozen. The hairline mask must be precise to allow the garment to sit under the hair without blurring the hair edges. - **Body Integrity:** The user's somatic structure must remain unaltered. While the source dress is fitted at the waist, the simulation must wrap the texture around the user's existing biometric measurements. Strictly prohibit any "slimming" algorithms; the garment must fit the user, the user must not be warped to fit the garment.
