TV is about to get a little more body positive, thanks to a brand-new documentary.

According to Glamour, a documentary called Straight/Curve will make its debut on EPIX on June 21. The film, which Glamour says “aims to redefine the beauty and size standards enforced by the fashion industry,” features prominent models like Iskra Lawrence, Denise Bidot and Charli Howard, all in an attempt to change the fashion industry.

Sharing their own struggles with body image issues, Glamour reports director Jenny McQuaile said the models help to shed light on a complex fashion environment, as the film examines “the misconceptions around health and size, body shame, the lack of diversity in fashion and media, and the limited scope of education in fashion schools, among other issues.”

Glamour also notes that the film features “Project Runway‘s Tim Gunn, and Chromat designer Becca McCharen, as well as Claire Mysko, CEO of the National Eating Disorders Association—all of whom are important in rounding out this conversation.”

Catch the film at 8 p.m. on EPIX on June 21.
