This is more than outstanding work! congratulations on the success could I ask how you made the native American leggins? did you have any blue prints/details on measurements etc? what materials did you use (guessing leather) and where did you buy it from? this would help a lot if you could answer this thanks!
I had no measurements or prints. I looked at the ref material available and drew there form out on paper. Then I started cutting away in real leather, sew it up and cutted some more. Luckily they could look rough so some cutting extra here and there didn;t matter.
Sounds like it was a blast! We just had our own event here in Australia - EB Expo, a gaming event similar to this. We debuted our AC3 cosplay and I can 100% agree with you - it gets very hot in the costumes! I crossplayed Sharpshooter and he has a billion layers lol.
