Soi Fon is a relatively short and petite woman with gray eyes and black hair. Her hair is worn short with two long braids bound in white cloth each ending in a large golden ring. 110 years ago, Soi Fon's hair was shoulder-length and had a softer look to it. She wears a traditional Shinigami captain's uniform with a sleeveless haori and a yellow obi tied around her waist. Soi Fon wears the uniform of the commander-in-chief of the Onmitsukido, which has no sleeves and doesn't cover the back, though she does wear long black arm bands. Instead of wearing the standard Shinigami sandals with tabi, she wears traditional Chinese shoes with ordinary white socks.
