It won't let me vote!!!!
Well, why not just have users explain in their posts? I chose the top one, the very first outfit. It's very bright and tomboyish, which is how I picture Human!Ruby, anyways
Since this poll is apparently still a little messed up, I'll just list these five choices in order of most to least preferred.The one I like most is #2, followed by #3, then #1, then the original, and the one I like the least is #4.
