Create a vertical 3:4 close beach portrait of a clearly adult East Asian woman, age 21, leaning playfully into the frame against a smooth blue sea. She has fair neutral skin, a petite adult frame, a softly tapered oval face, straight dark brows, large dark almond eyes, a small nose, rounded cheeks, glossy rose lips, and a bright relaxed smile with even teeth. Her long dark-brown hair falls in polished loose waves across her shoulders. She bends at the waist from camera-right toward camera-left, tilting her head strongly so her face forms a diagonal; she looks directly into the lens. She wears an ivory securely opaque halter swimsuit top with narrow neck straps, softly ruched shaped cups, a central gathered seam, and a supportive under-bust band. Preserve her natural covered chest-to-waist fullness—neither enlarged nor flattened. The shaped opaque cups, forward diagonal lean, realistic gravity, close slightly high camera, and cool sea bounce reveal the faithful contour while keeping the face dominant and all coverage secure. Crop from lower bust to above the hair, leaving generous blue negative space above and behind her. Use soft blue-hour light, subtle warm beauty fill on face, restrained specular highlights, clean skin texture, shallow focus, and a candid phone-camera immediacy without distortion. The attraction comes from direct eye contact, the off-axis lean, flowing hair, and spontaneous adult warmth. FIDELITY — HIGHEST PRIORITY: preserve the described face geometry, wavy hair, smile, petite proportions, exact ivory ruched halter top, diagonal lean, close crop, blue sea field, soft twilight palette, and playful mood. Apply only the stated adult age; do not redesign, beautify, slim, enlarge, flatten, or suppress curves. Remove logos, watermarks, text, IDs, and QR codes. Photorealistic, non-explicit.
