Returning for the 2025 revival are host Heidi Klum; Nina Garcia, reprising her role on the judging panel; and season 4 winner Christian Siriano as cast mentor, the position originally held by Tim Gunn.

Project Runway returns for Season 21 on Thursday, July 31 at 9/8c with a two-hour premiere on its new home, Freeform. But the network change - the fashion-design competition show previously aired on Lifetime and Bravo - is hardly the only change you'll see as the revived series undergoes a makeover following its two-year hiatus.
