Note that Zelena wears the hat in "Kansas", but not the cloak. She does not wear the cloak in any other episode either. However, the time of the tweet (March 11 2014) matches the filming of "Kansas" (this is based on trivia for filming locations for the previous episode, "A Curious Thing", and the next episode, "Snow Drifts"), therefore the photo is placed in the "Kansas" gallery.
