Female NPC Uniform

[Blanc - CPU White Heart]

Has anyone found out what uniform the female NPCs are wearing? The robe is definitely the Traditional School Robe but I noticed that their "Outfit" specifically is different to all of the uniforms I've found so far. The tops and skirts of the NPC girls are different colours for starters, since I'm in Slytherin my top is far greener than that of my female housemates, and their skirts are much longer. Also their ties [the Slytherin girls] are green and silver, whereas mine [on the Prefect School Uniform] is green and black. If anyone has figured it out please let me know, it's kinda been bugging me not having the same uniform lol

I've been wondering that too, I've played through the game twice and unlocked most of the clothing and so far I still don't have the same as the npcs which is kinda sad :c
The closest I can get is either the "Plaid Vest School Uniform" or "Plaid Shirt and Tie Uniform". Neither is identical but they're very close
