Poster sandal nữ êm chân dễ phối đồ

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 sandal reference. Show the female model wearing the sandals in a bright fashionable promotional poster. Include a bold Vietnamese headline "[headline]", a short subheadline "[subheadline]", one large hero pose, one close-up of the sandals on feet, and 3 smaller styling or comfort preview frames. The poster should feel modern, realistic, commercial, and easy to shop from. Preserve the model identity and keep the sandal design accurate. Use clean lighting, an attractive e-commerce layout, and clear product emphasis.
