They'd probably look different depending on their "Persona". Also completely my opinion:

Coward - Plain outfits (Afraid to show color)

Teacher's Pet - Quoted shirts at any color

Hero - Heroic shirts like superman shirts or even with a cape.

Social Butterfly - Changes every (day, week) for the new trend

Fragile - Long dresses/suits that hide their injuries, or anything really.

Evil - I doubt they'd even be a teacher but if they would, probably something scary, even if it's not halloween.
