The Demon Slayers might be famous for their sword-fighting skills, but let's not forget their iconic uniforms. They wear a black button-up pleated uniform embellished with white symbols on a thick collar. These symbols are indicative of their rank within the Demon Slayer Corps.
But the actual style statement is the Haori, a sort of coat worn over the uniform. Each character has a unique design that reflects their personality and style. Take Tanjiro, for instance. His Haori has a black-and-green checkerboard pattern, which has become his defining look.
