She was beautiful to begin with. Her nose was her only flaw. Way back when it was hook like, but like you said, la_angel, it was consistent with her ethnicity. Her ex, Carlo Ponti saw her as a "piece of clay that was ready to be a work of perfection" (actual quote). He literally "molded" her into what he saw fit, and she complied. She was much younger than he, and Ponti was funding her career and promoting it in everyway possible as well. She met him when he was a judge in a beauty pageant, where she was a participant.
Her features look distorted. She does not resemble herself. Loren looks good for her age, but she might have had an ameliorated visage currently, if she didn't "submit" to all the procedures she has undergone.
