Summer Portrait of Woman in Floral Dress by the Sea

Capture a young woman standing elegantly at a sunny coastal viewpoint. She's angled slightly towards the camera, one arm resting lightly on a black metal railing, with a calm, confident expression, looking directly at us. Her dark brown hair is loose, straight to slightly wavy, and gently wind-touched. She wears a flowing, lightweight blue summer dress with a vibrant floral pattern, sunglasses on her head. The background features the deep blue sea, rocky shoreline, and historic coastal buildings under a clear blue sky, evoking a bright, fresh Mediterranean summer mood.

The lighting should be natural daylight, soft sunlight with even illumination on her face, natural highlights, and gentle shadows. We want a highly photorealistic travel lifestyle portrait, capturing DSLR-quality realism with high detail and natural skin texture. Aim for moderate background blur. The overall feel should be elegant, serene, and vacation-inspired, with clean, vibrant coastal tones and high resolution.
