Vertical portrait full-body smartphone snapshot of a Korean beach, 4:5 framing.

SUBJECT: A beautiful Korean woman in her early twenties, about 163 cm tall, with fair natural skin and refined Korean facial features. Dark brown short bob hair tied into a small low ponytail, with sparse wispy bangs. Naturally slim build with realistic human proportions.
WARDROBE: A loose, oversized cropped knit sweater with pale yellow and white stripes, slipped down off one shoulder, exposing the shoulder line; ultra-low-rise white denim cut-off shorts worn at the very lowest point of her hip bones; cream-colored woven beach shoes; delicate silver jewelry; black sunglasses resting on top of her head.
POSE: Facing the camera, her body tilted slightly to one side. One arm raised high above her head, the oversized sleeve partially covering her hand; the other hand gripping the sleeve at her chest. One leg bears her weight while the other leg is bent backward behind her. Gentle, playful smile.
SCENE: A quiet Korean beach at low tide. Wet, reflective sand mirroring the sky, soft rolling waves, a few distant beachgoers far in the background, dramatic blue-gray clouds, soft sunset light.
CAMERA: Vertical 4:5 full-body smartphone photograph, 26 mm equivalent lens, taken by a friend standing 2 meters away at chest height. Natural perspective, background clearly recognizable, subtle smartphone HDR and fine grain.
STYLE: Casual summer vacation photography, soft coastal light, real skin texture, visible knit fabric texture, natural colors, authentic Instagram snapshot look.

Avoid: long hair, high-waisted shorts, unrealistic anatomy, exaggerated proportions, plastic skin, deformed limbs, extra fingers, CGI look, heavy background blur, studio lighting, text, watermark, logos.
