Fashion_Swap_Cascade, clothes_swapping, Photorealistic, hyperrealistic, 4K, cinematic lighting, studio background. A woman starts in a pastel pink sundress with thin straps. At 1.5s: grabs strap, pulls dress down, tosses to left — reveals a beige ribbed tank top + denim shorts. At 3.0s: hooks fingers under tank hem, peels it off upward, slings to right — reveals a red wool turtleneck sweater + black leather pants. At 4.5s: final pose in winter look, arms crossed, cozy smile. Biomechanically precise, realistic fabric physics, seamless continuity.
