Poster sandal cao gót quai mảnh

Create a complete vertical 9:16 promotional footwear thumbnail/poster, not a plain single image. Use [ảnh người mẫu] as the exact female model reference and [ảnh sản phẩm] as the exact sandal reference. Design a realistic Vietnamese poster for elegant thin-strap high heels. Show the female model wearing the exact sandals in a stylish full-body or half-body fashion pose, with the shoes clearly visible. Add a large product close-up, heel-detail inset, strap-detail panel, and 3 small supporting frames showing front, side, and on-foot views. Add a bold Vietnamese headline and a short subheadline. Clean, commercial, polished, feminine, and easy to understand. No watermark.
