Haha, umm... is the guy in the background of picture 3 named uhh... Kevin or something like that? And did he used to go to Green River?
Yeah, anyways, I promise I'm not a stalker, the person in your pic just looked really familiar, and I notice you live in WA too, so I thought I'd ask. ^_^;;;
Umm, basically most of my cosplay is based on pointing at a character and being like, "1. They're cool/I like them and 2. I look and act enough like them that I could pull it off and 3. I can sucker atleast one other person to do this anime with me."
Sorry, I know you were looking for actual suggestions... hmm... *dunno*
