Remember earlier this year when reader Julian Checkley showed us his Darth Malgus costume? As jaw-dropping as it was, this beats it.
This Tarfful suit is actually older than the Malgus outfit, but Julian's only just put a video together showing how it all works.
Taking over three months to build, it stands a whopping 8'2", meaning he has to wear stilts to even reach the head. He's also built a soundboard into the jaw, so that whenever Tarfful opens his mouth, wookiee noises come out.
To put this in context, this isn't a film set. Julian doesn't work for Lucasfilm. He's just a cosplayer, and built this whole thing himself.
