fujimaru ritsuka (female) (true ether chaldea uniform)
Female Ritsuka's version of the Mystic Code that her male counterpart wears in the Babylonia Singularity anime. Since it doesn't exist in the anime, this outfit is exclusive only to Fate/Grand Order. Female Ritsuka's version has her wearing knee-length white shorts and a cropped shirt that shows off her midriff and navel.
For Male Ritsuka's version, see fujimaru ritsuka (male) (true ether chaldea uniform).
