Did Coco Chanel go to university or college?

As far as is known, no. She may have served an apprenticeship in the Tailoring trades, By the way she was , originally, a Swiss!
Coco Chanel was taken as a charity case with her sisters to Notre Dame when Coco Chanel was around 17-18. This was after she was at Aubazine Orphanage. She was not pampered and neither were her sisters, but from the rich girls to good attitude she learned how to act rich!!!
