A woman starts in an oversized button-up shirt with bold green and turquoise wavy abstract patterns, paired with a fitted yellow crop top and high-waisted red denim mini skirt. At 1.5s: grabs collar of the patterned shirt with both hands, unbuttons it slowly from the top down — each button pops open realistically as she slides the sleeves off her shoulders. The fabric drapes naturally as she lets the shirt fall away to her left side. Simultaneously, she uses her right hand to lightly tug the hem of the yellow crop top — it peels upward smoothly, revealing a fitted coral-red ribbed tank top with thin spaghetti straps underneath. The crop top drifts downward, catching the light as it floats. At 3.0s: hooks fingers under the waistband of the red denim skirt with both hands, unzips it subtly at the side, then pushes it down her hips — it slides off smoothly, revealing matching high-waisted lime-green satin shorts with gold hardware. She lets the skirt drift away to her right side, arms moving gracefully. At 4.5s: final pose in new look — arms crossed, confident gaze, one hand lightly touching her collarbone. Biomechanically precise, realistic fabric physics, seamless continuity, soft studio lighting, shallow depth of field, rich color grading (green, turquoise, yellow, red, coral, lime)
