Smiling woman in pink bikini in shimmering blue water

A young woman with long, dark, wet hair and a radiant smile is posed chest-deep in clear, shimmering water. She is wearing a metallic pink bikini with thin straps. Her body is angled slightly towards the viewer, while her head is turned to the side, a joyful expression on her face. The background is a soft, out-of-focus expanse of blue, suggesting a bright, sunny day at the beach or a calm ocean. The lighting is natural and highlights the glistening water droplets on her skin and the sheen of her bikini. The composition is a close-up shot, focusing on the woman's upper body and face, with a shallow depth of field that blurs the background. The overall mood is one of carefree happiness and summer leisure. Photorealistic, high detail, natural lighting, shallowDOF, summer vibes.
