The fashion competition returns with Heidi Klum, Law Roach, and more of the industry’s biggest names.

LOS ANGELES — New season, same fierce runway – Project Runway returns to discover fashion’s next big star.

Twelve designers from diverse backgrounds will compete for a career-changing opportunity in this high-stakes reality competition.

“We’re in a new home, with new rules,” said returning host Heidi Klum.

She is joined by celebrity stylist and judge Law Roach, as well as Nina Garcia, editor-in-chief of Elle magazine. Christian Siriano, a former “Project Runway” winner and designer, acts as the mentor for contestants.

The competition is intense as designers aim to impress and make their mark. The trailer teases both dazzling designs and devastating blows.

“That is a grandma skirt, girl. And I love my grandma, but no,” Siriano says in one moment from the trailer.

This season highlights a celebrity-filled roster of guest judges, comprising Christian Cowan, Harris Reed, Jenna Lyons, Joan Smalls, Michael Kors, Mickey Guyton, Nikki Glaser, Sara Foster, Sofia Vergara, Tyra Banks, and Zac Posen.

“Project Runway” premieres July 31 on Freeform, Hulu and Disney+.
