I think
Okita Souji would love to wear it, so would
Harada Sanosuke I guess. And perhaps
Nagakura Sinpachi too.
Hijikata Toshizou would probably get furious when seeing his members' captains wearing it, thought I figure he would change his mind for the later shinsen's uniform. The western style attire for sure wasn't a good match with a pair of
geta, no?
I'll skip thinking about
Saitou Hajime♥ on it, he's way too out of character. Same case for
Yamanami Keisuke, and, whoa..., of course;
Kondou Asami.
Shinsegumi's Nike Air, anyone?
