Create a 9:16 vertical underwater fashion editorial poster. CUSTOM INPUTS: Subject: [Subject Appearance] Dress: [Dress Details] Handheld object: [Handheld Object] Pose and expression: [Pose and Expression] Main title: [Main Title] Small tagline: [Tagline] Color palette: [Color Palette] Show an adult woman floating naturally beneath the water surface. The upper part of the frame must clearly reveal realistic ripples, refraction, caustic highlights and a distorted partial reflection of the subject. She wears an elegant sculptural dress rather than a loose shirt. The design should reveal part of her shoulders, back, arms, waistline or legs, while the skirt and ribbons drift naturally through the water. Keep the body silhouette visible instead of covering her completely with fabric. The subject holds one visually recognizable object in her hand. The object should be large enough to read clearly, but must not block her face or body. It should interact naturally with underwater light, buoyancy and movement. Her long hair, dress, ribbons, bubbles and handheld object should follow a consistent water-current direction. Preserve believable underwater physics, natural fabric weight and subtle motion. Use cinematic blue underwater lighting with light beams entering from above or behind the subject. Add realistic skin texture, fine wet hair strands, small irregular bubbles and suspended particles. Keep the face clear, expressive and alive, without plastic skin or CGI smoothness. Build a refined fashion-magazine composition with strong negative space and editorial hierarchy. Integrate the exact main title “[MAIN TITLE]” into the scene using oversized high-contrast serif typography. Allow selected letters to be partially hidden behind the body, dress or object. Enhance the typography with subtle underwater refraction, stretched letterforms, translucent layering, displaced reflections and caustic light textures. Add the exact small tagline “[TAGLINE]” beneath it in a restrained layout.
