The designers team up in pairs with eliminated designers to create an avant-garde garment around one of the two astrological signs of their group. They had one day and 8 hours to complete the look. The night before the runway, they were brought to the American Museum of Natural History in New York. There the designers were greeted with surprise guest appearances of former Project Runway designers and winners Kara Janx, Alison Kelly, Jay McCarroll, Robert Plotkin, Christian Siriano, Daniel Vosovic, & Carmen Webber, who all voted on a winning look. This episode featured a surprise double elimination & the winner no longer had the advantage of immunity going forward.
