Season 1

Heidi Klum and Tim Gunn welcome 12 designers to New York City and tell them to pack their bags because their first fashion show will be in front of the Eiffel tower in Paris. In their first assignment, the designers must create a two-look brand snapshot. One designer lets self-doubt get in her way, while another has to make a new dress from scratch with only a few hours remaining.

Heidi and Tim meet up with the designers to give them their next assignment: a two-look, Haute-Couture inspired mini collection for a fashion show that will take place at the historic Musée Des Arts Décoratifs. As the fashion show draws near, an indecisive designer struggles to stay on track, while another designer attempts to push their creative boundaries.

In teams of two, the designers must blend their individual aesthetics into a three-look collection for a runway show on the banks of the River Seine. One designer struggles to overcome a teammate's mistake, while another pair of designers butt heads.

The competition heats up; Tim assigns the designers to create one look in seven hours, using only leftover fabric and supplies; the designers are pushed to their limits and fight for their spot in the competition, taking creative risks.

The five remaining designers are challenged to create a two-look collection and a digital marketing campaign. In addition to a fashion show, the designers will have to act as creative directors in a photo shoot with their models. In an epic and rainy fashion show, some of the designers shine, while others get washed out.

Tim and Heidi take the four remaining designers to a serene tea ceremony before revealing the next assignment. Now, the designers must create a two-to-four look mini-collection that embodies the evolution of their brands since the beginning of the competition. One competitor’s ambitious plan quickly unravels, while another decides to go big or go home.
