In 'Project Runway' season 4, which designer won the competition?

Christian Siriano won season 4 of 'Project Runway'. The season aired in 2007 and 2008, with Siriano defeating Rami Kashou and Jillian Lewis in the finale.

Siriano was known during the competition for dramatic designs, strong construction and a distinctive point of view. His victory launched a successful fashion career, including an independent label and later work designing for celebrities and public figures.

The season originally aired on Bravo, before the franchise moved to Lifetime. Heidi Klum hosted, while Michael Kors and Nina Garcia were judges and Tim Gunn served as mentor.

Christian Siriano is sometimes confused with later winners such as Leanne Marshall and Dmitry Sholokhov. Each won a different season, making the season number important when identifying the correct designer.
