There’s only a couple of episodes left before the Project Runway All Stars finale!

Tonight on Lifetime, a new episode airs of #PRAllStars and the guest judge is none other than Pharrell Williams. It looks like the dresses are made with some sort of glow in the dark tubing.

Watch the preview after the jump.

We predict that the winner will be Michael Costello, Austin Scarlett or Mondo Guerra. What do you think?
