In their first team challenge, the designers struggle to make their voices heard. However, this is an unconventional materials challenge and many of them stumble when forced to create a fashion forward look out of recyclable materials. Maggie Q and Anne Fulenwider join the judging panel.

Drawing inspiration from the hit film “Descendants 2,” the designers visit Lyndhurst Castle and are tasked with creating a look that represents “Good” or “Evil.” Most of the results are angelic, but as always, the devil is in the details. Dove Cameron and China Anne McClain guest judge.

The models become much more than runway eye candy as they serve for inspiration to the designers to create a street style look, to be featured in a photo shoot. But ceding creative control to the models proves to be a difficult chore for some designers. Guests judges are Georgina Chapman and Kelsea Ballerini.

It’s the JCPenney Challenge and the designers must use men’s fabrics and designs to create a fashion forward look for their female models. Not only that, they must work in teams to do it, leading to a runway elimination that no one saw coming! Asia Kate Dillon is guest judge.

The designers are tasked with creating an on-the-go look for friends and family of the Project Runway crew, but the good spirited challenge takes an ugly turn when accusations of cheating cloud the results of a contentious runway. Sophia Stallone and Yolanda Hadid guest judge.

The dramatic fallout from the cheating scandal rocks the designers and leaves everyone wondering how they’ll move forward in the competition. But the show must go on and the designers rally to create an Avant Garde look inspired by Shopkin’s characters. Kate Upton is guest judge.

It’s the Lexus Challenge, but this one is Unconventional and nobody is safe! The designers must use safety materials to create a look that wows the judges as Fashion Week is right around the corner. Guest judge is Carly Chaikin.

It’s an emotional Runway as the designers create looks inspired by “Warrior Women” — women who have battled breast cancer. Rachel Brosnahan guest judges.

The runway is converted into a Winter Wonderland as the designers are tasked with creating a winter-themed look that will decide who goes to NY Fashion Week and who gets left out in the cold. Guest judge is Katie Holmes.

After heading home to work on their Fashion Week collections, the five finalists are visited by Tim who is not impressed with everything they have created so far. The designers return to New York and present the judges with 2 pieces from their collection. With only three spots guaranteed for Fashion Week, everything is on the line.

Fashion Week is finally here and the designers rush to put the final touches on their collections. Four designers will have their dream of showing at New York Fashion Week, but only one designer will reach the next Project Runway Winner! Guest judge Jessica Alba joins the panel.
