Even though he's a male characters, I think his costume makes a wonderful female costume. I think I'm more psyched about this one since I think that it will flatter me better and it's easier and cheaper to make.
But on the other hand, this is a girl, the wings, though expensive, would be fun to wear (I would do them as simple white and black wings without the faces) and a tail is cool, though hard to make look good when it's that thick.
