EDIT Okay so when I posted this I was on a rant, and already knew the reasons behind why they dress as they are and whatnot, and don't need a briefing of their history, since a lot of people seemed to have done that already. XD It was simply a rant picture, nothing more.
You all saw it coming. They both have very similar colours and the use of stars/moons. What's with Sailor Moon being 14?? Wanna depend on a child to save you! And why does Wonder Woman wear a very American flag styled outfit? That's odd for a Greek Amazon to wear, isn't it? I haven't drawn an anime styled Sailor Moon for AGES! I used to always draw her as a kid, and I'm still getting used to Bruce Timm's style...
