I think I see a reason for the pants. Now, the first time I saw those I thought they were chaps, but someone(at S-D 1.0) told me no, that thing in the middle is the pants too, it just happens to LOOK like her, um, fur, whatever. I know my first reaction was to look and think, wait, DC can get away with that now? WTF is that?
And I would assume someone looking at her might be similarly distracted, more so than if she were just naked. I would assume that someone looking and trying to guess if that's really naked there or not would be a hell of a lot easier to kill.
That said, a costume seems superfluous with that character. Sufficient fur allows a lot of leeway.
