This Krystal cosplay hasn't debuted publicly yet, but you can check out lots of WIP photos from this painted bodysuit-based Krystal cosplay by Moonllita.
After a year of work, her commissioned Krystal suit (with Staff) is complete. No word yet on who bought her.
My auction win from Poland is here.
Another very photogenic human Krystal cosplayer appeared this year.
A new, fully-body Krystal fursuit has been constructed, though sadly is somewhat NSFW.
Ayano posted about another 2014 Krystal cosplayer in Japan.
