一名女子躺在白色沙灘上，身旁是碧綠海水

A high-resolution, candid full-body photograph of an athletic woman in her late 20s to early 30s with a toned, fit physique and sun-kissed tanned skin, reclining on a white sand beach near the gentle water's edge. She is lying back supported on one elbow, smiling radiantly, wearing a glossy metallic black string triangle bikini with metallic ring connectors and a tiny pink accent tag. Sleek wet-look hair pulled straight back into a neat bun or ponytail, green mirrored reflective aviator sunglasses, a delicate silver pendant necklace, and a metallic watch on her wrist. The background features shallow, crystal-clear turquoise ocean water gently lapping on wet sand, with low coastal cliffs and scrub vegetation under bright, natural midday sunlight. Shot on 35mm lens, f/4 aperture, sharp focus, natural skin texture, realistic reflections in sunglasses, photojournalistic beach photography style.
