Nagato in pretty much every costume she's ever appeared in. Props to anyone who can and is willing to add notes on the different versions of Nagato in this pic.

They even included the Gekisou and Gensou Yuki, whoever made this is brilliant!

There's also maid Yuki, who's slated to appear in Tsuisou (although I'm not sure if she's been in a maid outfit anywhere else, since the one in maid uniform is not wearing glasses like in Tsuisou)
