Create a photorealistic, softly romantic editorial portrait in vertical 9:16 format. The subject is a clearly adult 20-year-old Chinese woman with a petite adult frame, softly rounded shoulders, a naturally defined waist, graceful balanced curves, and realistic proportions. She has a gentle oval face, natural dark almond-shaped eyes, a delicate nose, softly curved lips, understated makeup, and very long, mostly straight dark chestnut hair.
She sits on shoreline rocks beside the sea at dusk. Frame her from the hips upward, with her head beginning near the upper quarter and generous pale sky above. Her torso faces slightly toward the camera, while her face turns into a right-facing profile, quietly looking out over the water. Her expression is serene and thoughtful. Her long hair cascades down her back and the left side of the frame; a few fine strands drift across her cheek and collarbone. Her forearms rest naturally toward her lap, cropped at the bottom.
She wears an opaque ivory off-the-shoulder dress with a fitted, softly folded bodice, a gently curved neckline, and loose ruffled sleeves falling below her shoulders to her elbows. The dress follows her natural waist and curves without exaggerated shaping. A thin silver necklace with a small oval sparkling pendant rests at the center of her upper chest.
A nearly level distant horizon sits around the upper quarter. Softly defocused waves fill the background, with only a few dark rocks near the bottom. The open sky transitions from pale cream and mint-gray to muted peach-pink at the horizon. The water reflects pearly lavender-gray. Use broad diffuse dusk light, delicate warm rim light on individual hairs, soft lifted shadows, restrained saturation, and gentle contrast. The face is a little brighter than the hair, while the ivory fabric retains its folds and subtle sheen.
Quiet, wistful, refined Chinese fashion portrait aesthetic. Shallow depth of field and creamy background blur; keep the face, pendant, and nearby fabric in clear focus. Fine natural skin texture, believable hair strands, realistic anatomy and cloth construction. No dramatic sun disk, no strong orange cast, no heavy makeup, no exaggerated bust or hips, no childlike body proportions, no transparent clothing, no plastic skin, no text, logos, signatures, or watermarks. Deliver a clean image.
