A high-quality, realistic vertical fashion photograph on a boat deck in the open sea. In the foreground, an adult woman with shoulder-length dark auburn hair is leaning against the railing, wearing a tight, fitted white long-sleeved crop top, white 3/4 leggings, and a wide-brimmed white sun hat. The fabric of her top and leggings is slightly damp from the sea spray, subtly hinting at the bright blue two-piece bikini worn underneath. She is looking toward the camera with a relaxed, joyful expression. The background shows the vast, sunlit ocean horizon. Professional fashion photography, sharp focus, frontal view, cinematic outdoor lighting, shallow depth of field. The depicted adult woman has shoulder-length dark auburn hair. Show her face clearly toward the camera at a mild three-quarter angle, large enough for a natural portrait face reference.
