Shinobu wears a dark purple standard Demon Slayer uniform with gold buttons, consisting of a dark-purple tinted straight-lined black jacket and matching colored tabi socks and hakama pants, tucked into white butterfly patterned Kyahan fading into pale turquoise then pink around her lower legs, fastened with white ribbons. According to Zenitsu, Shinobu is so cute, that she could make a living on her looks alone.
Shinobu is short in height and has been described as having a small and weak-looking build, which is later reinforced by her mentioning that she does not possess enough physical strength to decapitate a demon as the other Hashira do. She has center-split, ear-length, voluminous curtain bangs that flow down to frame the sides of her face, with two slightly thinner chin-length locks of hair in front of her ears below them. She has black wavy hair that fades to dark purple, styled at the back of her head into a flat yakai-maki bun, fastened with a white, turquoise and light purple butterfly ornament. Shinobu is a petite young woman with a slender build, and a pale complexion and large, compound-like eyes that lack pupils, only a haze of gradient purple, making her eyes appear similar to those of insects.
