Étendre un portrait pour une photo de site web

Extend the portrait downward to show more of her torso, framed down to the waist. Keep the existing image exactly as it is: face, expression, glasses, hair, cream t-shirt, lighting and plain white background unchanged. Add only the new area below: the same soft cream scoop-neck t-shirt continuing naturally down her torso with realistic folds, her body angled slightly as in the original, arms relaxed at her sides. Seamless join, same lighting and white background. Photorealistic. Portrait orientation.
