Jemima the Cat Costume for sale?

Does anyone have a Jemima costume for sale from Andrew Lloyd Webber's CATS The Musical? I am really needing one to own, not to rent or anything of that sort. Also, if anyone doesn't have one, if you made it, I would pay even more for that if I like it. Respond to this if you know of the costume being sold or you can make it, please and thank you :)
