Chanel was never tried for her crimes as a collaborator. She used her connections, information, and money to pay off the right people and cover her tracks.
She was briefly arrested and questioned by a French judge, but basically got off scott-free and allegedly told her family that she was freed by Winston Churchill.
Just so everyone is aware, Chanel S.A. is currently owned by the Wertheimers, a Jewish family that regained control of the brand after Coco tried to use her Nazi ties against them while the fled. Basically, at this point, it’s Chanel in name only.
