When I was first designing Jo, I will admit, I was pretty inspired by Korra's body type, although to be fair, Jo is a little more busty than Korra is. XD
So, I thought I was being clever while on barracks duty the other night to draw Jo in Korra's clothes. I think I had a point for this, but whatever it was, I lost track of it because it was late at night when I got the idea to draw this. Very late.
I purposefully used the opening sequence pose as reference, so it is most definitely not very original.
