i don't remember which one it is but butterick or mccall's has a formal dress pattern that is 90% perfect for trainers. all you have to do is alter the seams in the front where it does that cresant thingy. ^^ ainsyle, celesdragon, and i are making it right now. there are also a few others on c.com that are making them or have made them. look through the galleries because some were just recently posted. ^^
(also, next time post in the rikku ffx-2 thread. a mod will prob come by and close this later. ^^)
Excuse me, Please and Thank You will get you far in life.
