Phryne The Hetaera
Phryne's beauty was such that every important and rich man lined up to be with her. She was particularly...ummm...friendly with Praxiteles, the greatest sculptor of ancient times. He used her as the model for his most famous work, the Aphrodite of Knidus; that statue made Phryne the gold standard for female beauty for ages to come.
Phryne's habit of modeling as Aphrodite, the Goddess of Love, got her into trouble. Phryne was charged in Athens with impiety, the same charge that had got Socrates killed.
Needless to say, the best lawyer of the day was among her lovers. Hyperides struggled to save her, but he was failing because the complainants had her dead to rights; for a mortal to pretend to divine attributes was a crime. It looked like Phryne would be sent to her death.
With nothing to lose, Hyperides walked over to Phryne, standing in the court, and in one movement ripped down her dress.
The entire (all male) court took a close look at exhibit A.
The charges were dismissed.
Phryne thus became the only woman in history to be declared divinely beautiful, by order of court.
