Considering a good chunk of my guys are based on existing anime characters, I have a tendency to use them as my cosplay partners (i.e. grab a dollieh from the same series as a character I'm cosplaying). It's not technically cosplay for the dollieh I suppose, but hey, I have fun with it (and considering the characters I tend to cosplay, it's not like I usually have many human partners to cosplay with).
Example: me as Aina Sakhalin, and Ghinius as himself

I do have a few ideas in my head for more cosplay-type outfits for some of them. For example, when I get off my ass and make the Blue Meanie gijinka I've been wanting to do for a while I'm also going to make Jiri a Jeremy Hilary Boob, Phd outfit to go with (which all is from the non-anime though just as awesome
Yellow Submarine). I also shoved Shiro in a quick cosplay of "the Bandwagon" (AKA L from Death Note) Halloween a few years back, though I don't think that counts for terribly much because, well...
The thought of shoving Giren in an Akio Ohtori outfit when I finish him amuses me to no end.
