Nina Garcia guest judges on 'Project Runway All Stars'

Guest judges come and go on Project Runway, but’s no one who feels more comfortable in the seat than this week’s All Star guest judge: Nina Garcia. She brings her fashion industry knowledge as well as her years of Project Runway judgeship experience to critique the all stars’ looks.

This week’s challenge requires the designers to create a look that embodies their past, present, and future loves. And love is not what the judges had for Kate Pankoke’s dress. As expected, Nina did not go easy on the critique, but Kate—this being her third time on the show—proves hard to knock down.

Check out this exclusive clip to get all of the judges’ opinions… including a very well-placed eye roll from Isaac Mizrahi.

Project Runway All Stars airs on Thursdays at 9 p.m. ET on Lifetime.
