Thank you for the pictures, both links are working. I still say: "There are several cloak patterns you can alter. Try looking at the romantic cloak from Folkwear and there are several from Simplicity."
Also, the boots look like they can be bought and added to. Many of the cosplays I've seen look like they just used store bought knee pads. And the body suit can be made or bought. Try looking in a Bike shop for both the knee pads and suit.
Finally, I'd suggest PMing Starlit Rose,http://www.cosplay.com/costume/20776/
. She has the best cosplay of Chole I could find on this site and though my searching. Hopefully she can give suggestions. She made both the cloak and bodysuit from scratch.
