This must look like a premium real-world size range campaign, not an AI beauty collage. Use the same satin spaghetti-strap dress design on all four women, but make the garment fit truly realistic for sizes S, M, L, and XL. Each size must have proper grading, different seam behavior, different fabric pull, different waist and bust fit, different hip drape, and different hem fall according to the body. The four dresses are the same design in different soft pastel colorways: pastel yellow, pastel blue, pastel pink, and pastel green. Add refined butterfly embellishments or applique details that feel elegant and fashion-forward, not childish. The women should look like real fashion models in a commercial editorial studio shoot, with natural posture, slight human asymmetry, believable body diversity, realistic skin texture, and subtle expression variation. Add simple clean size labels below each model: S, M, L, XL."
