Sun Hat Beach Holiday Portrait

Create a photorealistic vertical beach portrait of a young woman with East Asian features standing by a turquoise tropical sea under a clear blue sky with a few soft white clouds. She is shown from the upper torso up in a three-quarter back pose, turning her head toward the camera with a calm, subtle smile and direct relaxed eye contact. She has black hair loosely tied in a low messy bun, with a few windblown strands across her cheek. She wears a wide-brim natural straw sun hat with an open woven texture and a dark navy rim, holding the brim lightly with one hand. The hat casts delicate dotted lattice shadows across her face, shoulder, neck, and upper back. Her outfit is a white off-shoulder eyelet lace summer blouse with floral cutout embroidery and ruffled neckline, with thin swimsuit or camisole straps visible on one shoulder. Use bright midday sunlight, crisp natural color, shallow depth of field, softly blurred ocean horizon and distant island on the left, realistic skin texture, beach vacation fashion editorial mood, 9:16 vertical composition, subject centered slightly right, no text, no watermark.
