I have no idea really, I was just looking up japanese fashion on pinterst and that was what people mentioned in posts about the outfits I thought Pris might make for Key.

Oh, and for the cosplay idea, I figured out how to tie it in. I had this idea that Priscilla sneaked watching Cardcaptor Sakura into her education by saying that the french dub would help her learn the language, and her love of sewing is in part because of all the costumes Tomoyo made for Sakura.
