Create a highly detailed and realistic image of a young woman in her twenties. She has long, flowing brunette hair and captivating light-colored eyes. Her skin has a soft, sun-kissed tan, giving her a healthy glow. She has a fit, athletic physique, typical of a fitness model, with well-defined muscles and a large chest. The image should be framed as a close-up portrait, suitable for an Instagram profile picture, with her wearing a stylish outfit that highlights her curves, and a confident, alluring expression.
