He is a male character of Dangan Ronpa, but he looks really like a girl and is usually dressed as a girl at school. He is Chihiro Fujisaki who is a meek and timid boy with short brown hair and eyes. And this dark green and brown school uniform is his typical costume in this series, which is made up of green and white jacket, white shirt underneath and brown skirt with suspenders. It is really a cute anime costume for cosplay girls.
Obviously, this Chihiro Fujisaki outfit is more suitable for females, and also is more popular with girls. Of course, it would be a special experience for some boys if you want to give it a try. In one word, this cute school uniform is a good idea for small and cute cosplayers.
