Project Runway Season 4 was the fourth season of Project Runway, Bravo's reality competition for fashion designers. The season premiered November 14, 2007. Returning as judges were supermodel Heidi Klum; fashion designer Michael Kors; and Nina Garcia, Elle magazine fashion director. Tim Gunn, chief creative officer at Liz Claiborne, Inc., again acts as a mentor to the contestants.
Through a series of weekly challenges, contestants were eliminated, leaving three finalists left who then went on to show their designs in the final episodes at New York Fashion Week. The winner, Christian Siriano, received prizes including: an editorial feature in Elle, $100,000 from TRESemmé to start his own line, the opportunity to sell a fashion line on Bluefly.com, and a 2008 Saturn Astra automobile. Siriano mentors the designers on Project Runway from season 17.
Elisa Jimenez, Sweet P Vaughn and Rami Kashou later appeared in Project Runway: All Stars in 2012, where Elisa placed 13th, Sweet P Placed 12th, and Rami came in 8th place out of 13. In 2014, Chris March appeared in the fourth season of All Stars, coming in 12th place out of 14.
