Well, I commission stuff :3, but i gotta say this is one of my more expensive cosplays due to the sheer amount of fabric. My first one which wasn't nearly as long was still at least 8 yards of both the chiffon and satin. you can see the old version in the first pics i put up of my serenity. Then i added about 20 yards of fabric to it to give it that dramatic length.
I can make one if you are willing to pay the commission price for it.
