I believe that was something you could get on a VMK T-Shirt. That was a custom picture I believe, but No that is not real and has never been seen or heard of in the game. Although that hat and pants are blinding..
I know my mom and I have been waiting anxiously ever since we heard there was going to be a girl pirate outfit. But last year around Christmas we asked Yavin and he said "Maybe next year" so hopefuly it will be because my mom is going to go nuts waiting for it!!
