Poster quần jeans nữ tôn dáng

Create a complete vertical 9:16 promotional thumbnail/poster, not a plain single image. Use [ảnh người mẫu] as the female model identity reference and [ảnh sản phẩm] as the exact jeans reference. Show the female model wearing the exact jeans in a polished fashion e-commerce poster. Include a bold Vietnamese headline "[headline]", a short subheadline "[subheadline]", one large hero frame, a close-up of denim texture and waistline details, and 3 small styling preview frames. The composition should be realistic, commercial, fashionable, and easy to understand. Preserve the model identity and the exact jeans silhouette, wash color, and fit. Use flattering but natural lighting and a clean promotional layout.
