As part of my training, I designed Orestes’ costume for Jean-Paul Sartre’s play « Les Mouches », as well as drawings of the other characters and a model of the set design. My concept combines the aesthetics of ancient Greece with those of the 1940s. Oreste first appears wearing a heavy cape, symbolising the weight of his teacher’s highly intellectual philosophy. When he chooses to kill his mother, he frees himself from this burden and reveals his true face: that of a provocative, free and existentialist Zazou. His yellow tartan costume, a fabric emblematic of the Zazous and a sign of resistance to the Nazis, expresses light and the path to freedom, while his draped shirt and accessories are reminiscent of ancient Greece. The other characters continue this dialogue between antiquity and modern times: Jupiter, adorned in gold and an imposing cloak inspired by Nazi generals; Egisthe and Clytemnestre, evoking Marshal Pétain and his wife; the teacher, a figure of the 1940s intellectual in a turtleneck and corduroy. The people, forced into perpetual mourning, are dressed in black, with red shoes symbolising guilt and blood. Finally, Electra moves from servitude to rebellion: her white costume, inspired by the Zazous and embellished with ancient drapery, illustrates her hymn to joy and her quest for liberation.
