The friend knows she's transgressing and is likely aware that her actions would be seen as wrong, even if it’s appealing to her superficial desires.
You expressed your feelings of displeasure already; unless she brings it up again, there may not be more to say without damaging the friendship.
You can choose how to react: either continue your friendship despite her actions or distance yourself if you find her behavior unacceptable.
True friendship may involve helping her when she faces consequences in the future, rather than continually admonishing her for her choices.
