Woman Floating in Reflective Water

Create a photorealistic overhead fashion editorial image of {argument name="subject" default="an adult woman"} floating on her back in deep blue water, viewed from above at a slight diagonal angle. She wears a translucent wet {argument name="dress color" default="white"} Grecian-style chiffon dress with gathered pleated cups, delicate shoulder draping, long sheer sleeves, and a cinched ruched waist; the fabric clings softly while remaining tasteful and non-explicit. Her long {argument name="hair color" default="dark brown"} hair fans partially into the water, and her head is tilted back with the face intentionally obscured by a plain square block matching warm skin tones, centered over the face. The water surface is clear and glossy, with ripples around her shoulders and hair, bright sun glints, and pale cloud reflections across the upper half of the frame. Use natural daylight, cinematic realism, soft highlights on wet skin and fabric, a serene dreamlike mood, high detail, vertical 4:5 composition, no text, no watermark, no extra people or objects.
