Same as Project Runway, All Stars follows the same format with challenges, judgings, and eliminations.
Judging
Judging duties on the first season of All Stars were taken up by host, Angela Lindvall, fashion designers Georgina Chapman, Isaac Mizrahi, and a fourth guest judge, usually a fashion designer, a supermodel, a celebrity, or a professional from an industry related to the challenge given. The second season saw the replacement of Lindvall as host and judge by supermodel Carolyn Murphy, who only remained with the show for one season also. American actress Alyssa Milano became the host and judge on All Stars in the third season, and has remained on the show for five seasons. Joanna Coles acts as a mentor to the designers, giving them suggestions and tips for their designs throughout the episode, but she does not participate in the judging's. Coles was the stable mentor for the first and second season, until Zanna Roberts Rassi replaced her in the third to fifth season. Anne Fulenwider took over for final two seasons.
