The Lifetime series “Project Runway” is going where it has never gone before with its upcoming 16th season, which will celebrate body diversity with what the show calls “size-inclusive models.”

“As a true reflection of all women across the country, models range from 0 to 22, and this season’s designers must show off their skills and ability to make stunning creations for any size,” the show announced this week. The season premieres Thursday, Aug. 17, with Heidi Klum and Tim Gunn back as hosts.

Guest judges during the season will include Demi Lovato, Katie Holmes, Olivia Munn, Yolanda Hadid and Kate Upton.
