Create a close-up portrait of a fit adult female with long dark hair, styled in loose waves, wearing large black-framed glasses and a white strapless top. The subject is positioned slightly to the left, with her arm raised above her head, showcasing her muscular arms and toned shoulders. The background features soft, diffused natural light streaming through sheer curtains, creating a serene atmosphere. The camera angle is slightly elevated, focusing on the upper body, emphasizing the texture of her skin and the fabric of her top. The lighting is gentle and even, likely from an overcast sky or early morning sun, with subtle shadows adding depth to the image. The overall mood is calm and natural.
