I have absolutely NO idea what this is from, but it looked so amazing, I couldn’t not take a picture. Look at that wig!? Skills.
Update: Celestia Ludenberg from Dangan Rompa!

An interesting combination of costumes at the Ottawa Geek Market back in April: the human muscular system and Attack on Titan’s Mikasa. It works for me, though!
Edited: the human muscular system is apparently a colossal titan from Attack on Titan. The more you know! Not such an unusual combination after all!
