Generate a close-up, high-resolution shot focused on the detailed texture of the fabric as the model stretches. Shot in 4K resolution, use a macro lens for extreme detail on the activewear leggings and bra, showing the stretch and flexibility of the material. The lighting is soft but directional, casting shadows that emphasize the fabric folds and the model’s toned body. The background is slightly blurred to keep the focus entirely on the outfit's details and the body’s movement. Enhance the image with HDR effects for depth, and add fine-tuned sharpening in Photoshop to accentuate the texture and minute details of the outfit.
