About Project Runway (US) Season 18, Episode 12 : The Height of Avant Garde Fashion

With only one challenge left to make it to New York Fashion Week, the remaining designers must think big to create an avant-garde look that is anything but ordinary. In a fashion first, the runway begins with a season long retrospective, outside and 16 stories high, at New York City's dramatic, Vessel. The stakes are as high as the runway, because in fashion one day you're in, and in this challenge, two will be out.  Guest Stars: Rachel Brosnahan,
