Ok, so last part: the dress and Aang.
I stayed up until 10 the night before the convention modifying the dress, which I cut to look like this:
and added trim with fabric similar to this.
And that's it, really. On the day of the con I did smokey eyeshadow with red in the crease, and did general cosplay makeup... yep. I did most of it in the car lol.
For Aang we got a yard and a half of orange fabric, a yard of yellow fabric, and some red woven material. We basically safety pinned it like a toga. He wore brown pants, black tennis shoes, and a wig cap that I painted the arrow over.
So, yep, that's it! I'll have a post about the convention (and pics) up soon!
Oh! And I found this on tumblr... if you scroll down, the second picture is of my brother and I! http://humanitys-cutest-soldier.tumblr.com/post/81948871086/kraken-con-spring-2014-was-an-absolute-blast
