Woman in green bikini posing in clear shallow water

A beautiful young woman with long, dark, flowing hair and a fair complexion is posing in clear, shallow water. She is wearing a vibrant green bikini with string ties. Her expression is subtly alluring as she looks slightly downwards. She is wearing large, dark, rectangular sunglasses that obscure her eyes. The water is crystal clear, revealing the sandy bottom beneath. The lighting suggests a bright, sunny day, casting subtle shadows on her skin and creating dappled light effects on the water's surface. The shot is a medium close-up, focusing on the woman from her upper chest to her mid-thighs. The composition is balanced, with the woman slightly off-center to the right. The overall mood is relaxed, summery, and sensual, with a realistic, photographic aesthetic. The depth of field is shallow, with the water in the foreground and background slightly blurred, drawing attention to the subject. The image has high detail and sharp focus on the woman.
