Bikini Beach Portrait AI Image Prompt

A realistic 9:16 beach portrait. A fictional adult woman, not a real person, appearing in her {argument name="age" default="mid-20s"}. Position the woman in the center of the screen, with the center of her face aligned to approximately 50% of the width, and the visual center including her wet hair, shoulders, and upper body also at 50%. The top of her head is just inside the upper edge, her face around the top 18%, her upper body in the center, with her leaning forward naturally connecting her arms and hands to the bottom. She faces the camera, lowering her hips and leaning forward slightly, laughing openly without shrugging. A bright smile that makes her eyes squint, mouth naturally open, teeth aligned but not overly uniform. Healthy contours, natural rounded cheeks, subtle glow on wet skin, and a bright complexion. Dark brown medium hair, nearly black, wet from seawater with thin strands irregularly along her forehead, temples, and cheeks, the rest flowing behind her shoulders. Do not make the hair voluminous or dry; draw wet clumps and tiny water droplets for each strand. Her outfit is a solid {argument name="swimsuit color" default="deep navy blue"} halter neck bikini top. Express thin straps, natural fabric stretch, and subtle shades of wet fabric, avoiding excessive exposure or unnatural body exaggeration. The posture is innocent and sporty, making summer fun and freshness the main focus rather than sexiness. Both arms lowered in front of the body, with anatomically accurate connections of elbows, wrists, and fingers. Do not cut off important fingers at the edge; ensure five fingers per hand with natural overlap and joint direction. Foreground is pale white sand and very shallow transparent seawater, the woman in the middle ground, and the background is a bright sea surface dissolving from white into light turquoise. Horizon lines and buildings are not emphasized, blurring the background into a clean, minimal aesthetic. Small white reflections and soft blue-green gradients on the sea surface, with tiny waves and bubbles near her feet. Camera slightly higher than the woman's chest, frontal, close range. Focal length around 50mm, natural perspective on face and upper body, no extreme wide-angle distortion. Shallow depth of field but face, hair, shoulders, and the front of the bikini are sufficiently resolved, with only the background smoothly blurred. Light is a large, soft daylight like an overcast sky or bright shade from the top front. Avoid hard shadows, leaving uniform light on both sides of the face and faint shadows under the chin and inside the arms. Color temperature is slightly cool and neutral, exposure leaning high-key but without blowing out whites, and skin tone is natural. Overall color scheme is navy, white, and pale aqua blue. Natural pores, fine water droplets, and slight redness remain on the skin, avoiding excessive smoothing or plastic feel. Tiny, natural catchlights in the eyes, low moist gloss on the hair, and fine weave and wet texture on the fabric. High-quality commercial photography, clean background, natural smile, realistic human body, consistent light and shadow. No text, logos, brand names, signatures, or watermarks. Avoid extra people, extra arms or fingers, missing fingers, fused hands, asymmetrical eyes, double teeth, unnatural chest area, melted fabric, floating droplets, doll-like skin, excessive HDR, over-sharpening, or illustrative style.
