Or would it be just "uniform"? "sailor_uniform"? I'm not even sure.

Was tagging a picture to discover serafuku is very underused.
(Never done this before, please forgive my mistakes!)

I think it should imply clothing instead of aliased imo. It's a type of clothing and sometimes it's not considered a uniform

Yeah, I guess that makes sense. But I thought it would be aliased since some people would have a fetish for school uniforms.
