I'm writing a fic, and this has been bugging at me. What exactly do the robes look like? Are there differences between the robes of Slytherins and Gryffindors, and so on? Do you suppose the robes have been changed in style since any older time?
This has really been bothering me, and I can't find anything that's better than movie canon (which isn't true in this case, I know). Thank you all in advance for your help!
