Harry Potter Sweater I'm Looking For A Sweater That Was Worn In The Latest Harry Potter Movie.?

I'm looking for a sweater that was worn in the latest harry potter movie.? - harry potter sweater

So in the end, Emma Watson has a gray sweater, very nice, and I wonder where I could find - not through the door, but the shop that sells them. I understand that this is not likely to happen, but if I know that would be fabulous. Thank you!
