Create a vertical 3:4 blue-hour beach fashion portrait of a clearly adult East Asian woman, age 21, standing in shallow calm seawater. She has a petite frame with natural adult proportions, fair neutral skin, a softly tapered oval face, straight dark brows, dark almond eyes, a small straight nose, a warm closed-tooth smile, and long glossy dark-brown hair flowing to mid-back with soft face-framing strands. She turns her torso three-quarters away while looking back toward the camera; one hand lifts to touch the back of her hair, the other arm rests long at her side. She wears a minimalist ivory two-piece swimsuit: a securely opaque halter top with narrow neck ties, shaped cups and supportive under-bust seam, and matching mid-rise ruched briefs with full secure coverage. Preserve her natural petite waist-to-hip transition and covered torso fullness—neither enlarged nor flattened. The three-quarter rotation, gentle hip shift, halter tailoring, realistic fabric tension, arm-length camera distance, and cool ocean bounce create the silhouette without anatomy-centered framing. Crop from upper thighs to above the head, placing her against an uninterrupted blue sea with no visible horizon. Use soft twilight illumination, subtle cool fill, a faint warm facial key, low contrast, authentic skin texture, slight sea breeze in hair, clean lens rendering, and fine portrait grain. The mood is relaxed sea-breeze confidence with approachable adult warmth. FIDELITY — HIGHEST PRIORITY: preserve the described face, long hair, petite proportions, ivory halter swimsuit construction, hair-touch gesture, three-quarter look-back pose, upper-thigh crop, blue water background, twilight palette, and gentle smile. 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, secure swimwear coverage, non-explicit.
