^_^ I know this reply is a little late, but I'm actually going to be pulling a Dilandau cosplay for Otakon, and I'll be bringing Shesta with me. Ditto on the real leather, the suede, the heavy, hard armor, and all of that goodness. And we -were- looking for a Van to slap around....
...and for the record, if anyone out there can play a GOOD Dallet or Miguel or Gatti, ect, I'd be happy to help make the costume, including providing detailed directions on how to make all of the armor and the coat, as well as where to purchase all of the proper materials.
You can get ahold of me at Jean@boboki.com
if you're interested.
