A realistic image of a young 20 year old girl with long, blonde hair styled in loose waves, sitting in a brightly lit room. She is dressed in a cropped, light grey tank top that reveals her body, and she is wearing white ankle socks. The girl is sitting on a windowsill, with her legs slightly apart. The natural light from the window illuminates her toned physique, highlighting the contours of her body. The overall atmosphere should be soft and airy, with a focus on the woman's confident and relaxed pose.
