It's the halfway point and the designers are hitting the road to a denim explosion. In a Project Runway throwback challenge, they'll create all-denim looks while competing in head-to-head battles where only one designer can be safe from elimination. Uncut Gems star Julia Fox - a model, actress and It girl of fashion - and designer Willy Chavarria guest judge and weigh in on the exuberant uses of denim.

Hold on to your seats, because Project Runway is about to make history! For the first time, our final seven designers are given the freedom to design whatever they want for this challenge. On the grand outdoor runway of Franklin D. Roosevelt Four Freedoms State Park, their daring "freedom looks" will be unveiled, rain or shine. It's a high-stakes test of creativity. Who will ride the winds of this newfound creative freedom to victory, and who will spiral into defeat?
