I have bunny ears and a bunny tail. You might have to try the Restaffs or the general resources ->generator parts list for the outfit. I've seen a few variations, but since I never liked that style, I don't keep track of it. I think whitewitchstudios has a few bunny girls you can use if all else fails.
I'm sure this question's been asked before, but I can't find an answer: is there any way to run the Steam version of RPGMaker *without* being logged into Steam? It's a frustrating extra step sometimes.
