Create a luxury fashion advertisement in the style of a mural. The design should be bold, graphic, simple, and minimalistic, focusing on clean lines and striking visuals. Incorporate a helix shell, a butterfly, and a lotus flower as central elements, each representing elegance, transformation, and purity respectively. The composition should be harmonious and visually appealing, with each element seamlessly integrated into the mural. Use a sophisticated color palette that emphasizes luxury, with perhaps a touch of metallic accents. The overall aesthetic should convey a sense of high-end fashion while maintaining an artistic and modern mural style.
