Which French playwright collaborated with Coco Chanel on costume designs?

Jean Cocteau collaborated with Coco Chanel on costume designs.

Cocteau was a French poet, playwright, filmmaker, and visual artist whose work crossed many disciplines. Chanel designed costumes for productions connected with his theatrical and cinematic projects, including his 1923 play Antigone.

Their collaboration reflected the close relationship between Paris fashion and the avant-garde arts during the early twentieth century. Chanel’s designs could support a modern stage image without relying on the elaborate historical decoration common in older theatrical costume traditions.

Cocteau is also connected with Le Train Bleu through the ballet’s scenario, but that production involved a wider group of artists. The playwright’s name is the specific answer for Chanel’s documented theatrical collaboration.
