Best plave for Black Bulls robe merch?

I just found out that my niece loves Black Clover, and I figured the best holiday gift for a fan of the series would be none other than the iconic robe. I was doing some research and found some options, but since none of them are official I'm worried about the quality. So does anyone here have any recommendations for where to buy one? It looks like the Crunchyroll store doesn't sell them anymore, in case anyone was going to bring that up.
