Its between Kitana's Deadly Alliance primary and MK2011 primary for me. They're both excellent designs with her looking like a fighter, but at the same time regal and well, Princess-like. Her MK vs DC I felt had a bit too much black, but it wasn't by any means BAD.
Yes the animation for the hair is pretty bad, it would have been cool to see the mk characters with the same graphical detail and animation as the characters in say soul calibur. i guess that was outside of netherealm's capabilities though. and yeah it definitely is the most royal looking costume, i rather like it
