Fourteen designers from across 19 seasons of "Project Runway" descend on New York once again to vie for the coveted title that has eluded them all. The iconic designers meet one another and catch up on their successes after leaving the Runway.

For their first challenge of the competition, the designers have to rewrite history by reinventing the look that either got them eliminated or gave them the lowest score in their past, and turn it into a high-fashion moment for the runways of today.

The all-stars are tasked with creating a runway look using toys for FAO Schwarz.

For Coronation Day, the designers are blindly paired together and tasked with creating couture modern gowns that exemplify royalty; Wes Gordon, the Creative Director of Carolina Herrera and gown expert, serves as a guest judge.

The designers are forced to share a single bolt of fabric to demonstrate how they can stand out from one another and prove why they're the top designer; actor, producer and Emmy Award-winning writer Lena Waithe joins as guest judge.

The designers must create chic and cohesive mini-collections inspired by the '90s; designers take to the halls of a New York City high school to showcase their styles, all while trying to impress guest judge Jennie Garth.

The jockstrap is back; the all-stars must create high-fashion looks featuring couture undergarments in this one-day challenge; fashion icons Sergio Hudson and Paulina Porizkova help separate the hot from the not.

It’s the halfway point and the designers are hitting the road to a denim explosion; in a throwback challenge, they’ll create all denim looks while competing in head-to-head battles where only one designer can be safe from elimination.

Fan favorites from the cast of "Below Deck" walk the runway in the infamous Real Client Challenge; Real Housewife Luann de Lesseps and former Below Decker Kate Chastain guest judge to help the panel decide who will sink or swim.

For the first time, the final seven designers are given the freedom to design whatever they want; on the grand outdoor runway of Franklin D. Roosevelt Four Freedoms State Park, their daring "freedom looks" will be unveiled, rain or shine.

The designers are faced with one of their hardest tasks yet: a one-day challenge that forces them to create one runway look that showcases two opposing fashion styles.

The final four designers push themselves higher than ever for the Avant-Garde Challenge, inspired by the breathtaking views of Manhattan from the 91st floor of Summit One Vanderbilt; famed stylist Law Roach and Steven Kolb from the CFDA guest judge.

In a "Project Runway" first, three all-star finalists race against the clock to complete eight finale-worthy looks in just eight days; with the pressure mounting, all these finalists are shining jewels, but only one will be crowned.
