Generate a 9:16 vertical photorealistic summer meadow portrait of a beautiful adult East Asian young woman lying naturally in the grass. She has a refined, attractive face, bright expressive eyes, soft lips, natural skin texture, and long dark hair with loose strands and a slight breeze effect. She looks directly at the camera with a soft, intimate, slightly flirtatious gaze and a gentle smile. Her figure is slim with elegant feminine curves, and she is wearing a white spaghetti-strap lace dress. Her body, hair, and dress are naturally pressed into the vivid green meadow, surrounded by tiny yellow flowers. The setting includes distant hills, blue sky, and soft summer sunlight, with fresh, clean, airy colors. Shot as low-angle close-up outdoor portrait photography, 85mm lens, shallow depth of field, slightly blurred foreground grass, realistic skin, realistic grass, and a subtle dreamy summer mood. Avoid plastic skin, fake background, stiff pose, distorted hands, neon green grass, and CGI feel.
