So for halloween, my sister and I are doing another twin cosplay since our last one was so successful. I actually ordered my school robe from amazon and I just received it a couple of days ago. It's good quality for the price I paid for it. It was cheaper and is better quality then a halloween store harry potter robe. It's not as high quality as robe from the wizarding world of Harry Potter shop would be but it didn't cost $100. For underneath the robe, I'm just dueing a plain while blouse but with a black skirt instead of a grey skirt since I have that in my closet. My next step is to make the maudaurs map and buy a replica of fred weasley's wand.
