I made this costume for Celebration 5 a couple of years ago. I hated the way I originally had trouble the orange make up but I was able to correct it for Dragon Con several weeks after C5. This costume was a collaborative effort between Webchief, Lonewolf 1183, and I. Here's the link to my original in progress thread: http://www.therpf.com/f24/ahsoka-tano-final-pics-88315/
I have attempted to sell this costume to move on to other projects but since I haven't been able to find anyone to buy it, I'll probably wear it to Celebration 6 this August.
