Reality TV show: Project Runway (2007-2008)

Siriano, the youngest designer to be crowned the winner of Project Runway, beat out the competition for both the title and was also the fan favorite, but the guy honestly didn't even need the win—the publicity he and his crazy couture designs scored from his appearance on the show's fourth season would've been more than enough.

Unlike other struggling contestants, Siriano's time on Bravo served as a serious launching pad for his career. Since being propelled into the spotlight, he's cranked out collections and collaborations that can be found at the likes of Saks Fifth Avenue, Neiman Marcus, Payless, Victoria's Secret, and more.
