When I posted my Yuna cosplay, I came across a website that hosts resources for all the dresspheres from Final Fantasy X-2. Since my post went up, they have added my "tutorial" to their list! I'm very proud to be a part of this collection and I highly recommend checking it out next time you wanna make a FFX-2 cosplay.
Check out the Gunner page here and browse around the other dressphere resources while you're there.
