This is actually a spoiler for the comic story line, but I don't think people will be able to figure it out so I posted because it was pretty.
This IS NOT a redesign, mind you, it's concept artwork for a certain stage in her story. This was meant to seem more...warrior like compared to her assassin outfit. I wanted to keep the armor relatively light weight since she's meant to be fast yet protective against small attacks. I also didn't want to stray away from her actual design.
And yes, I messed up on her proportions slightly, no need to remind me in comments.
EDIT: The skirt/armor portion was lengthened so it looked more protective and her hair was changed to show physical change. Some time will pass and many events will happen before she wears this armor. Everything else was left unchanged and the leg armor underneath is still the same even if you can't see it anymore.
