I know this is obscure, but I've been talking about it for months. Here it is.
Juri dressed as Zafina from Street Fighter X Tekken.
Every character in the game got an alternate costumes based on a fighter from the other series. I cosplay Juri a lot. My main Tekken cosplay is Zafina. So when the two combined, I lost my mind. Then I made the costume.
