Project Runway (season 4)

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, Karen Claybrook, 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.

This season was preceded by Season 3, and followed by Season 5 on July 16, 2008.
