In a twist that may feel more like a trick to the designers, it's an overnight challenge! The designers go all out to complete their high end looks.

Designers are paired with real athletes who are competing to be in the 2020 Summer Olympic and Paralympic games and the designers need to make their dream outfit for a victory night celebration.

The remaining designers must think big to make an avant-garde look that is extraordinary and in a fashion first, the runway starts with a season long retrospective, outside and 16 stories high, in New York City.

Christian visits the remaining contestants at home as they complete their final collections, but then it's back to the workroom to refine and revise, because even though New York fashion is here, that doesn't mean everybody will show.

The remaining designers hurry to put the final touches on their collections, balancing advice from pros while attempting not to lose their own point of view and it's game, set, match when Serena Williams joins as a guest judge for the final runway.

The designers are split into two teams living and working separately to create mini-collections celebrating color; the competition comes to a head on the day of the runway show when they reunite hoping their team is victorious.
