I wouldn't be surprised if some schools (fictional or real) had both students and falculty wear the same basic uniform. I'll go look to see if any details on Cinder's uniform are different tomorrow. (I live in PA, want to go to bed soonish). If I find any, they might indicate someone is a teacher rather then a student, but then again, the obvious counter-example would be Ruby and her cape.
