Can Austin Scarlett finally sew up a win on Project Runway? Or is it Mondo Guerra's turn to take to the victory catwalk?

On Thursday at 9/8c on Lifetime, Project Runway returns with a special All Stars edition that brings back 13 designers. With a new host, supermodel Angela Lindvall, judges — design icon Isaac Mizrahi and Marchesa co-founder Georgina Chapman — and Marie Claire Editor-in-Chief Joanna Coles as mentor, Project Runway will not only look different but feel different as well.
