For Dragon*Con 2010 I magically produced a Cassie Sandsmark costume.
The shirt was a black t-shirt I had, which I cut up and modified heavily (because I was lazy). The symbol I made and inset into the shirt. The necklace was made by me.
The stars are foam pieces that *Stargazer-Gemini
cut out for me, which I then spray-adhered to metallic spandex, and then glued the edges. They were all handsewn on to some red pants by me, *Stargazer-Gemini
The bracers were made by *Stargazer-Gemini
similarly to the stars. They attach together with snaps. The wig was styled by *The-Cosplay-Scion
to wear for our Powerpuff Girls group, and it worked.
All in all, I actually kinda like this costume.
