I definitely agree with the over-designed complaint but that's kind of a trademark of Injustice (and Netherrealm at this point -- I thought MK9 had way better designs than MKX).
That being said, if someone showed me her out of context and asked, "Who is this," I would need to think about it for a minute. At least with the other over-designed characters I know who it is in a split second moment.
I don't think the costume is that different from say her look in the new 52 run of Birds of Prey. Seems to be a mix of modern styles actually as she didn't have the jacket in that run from what I remember.
