Fashion has a long-term problem with size, but this new documentary is looking to confront it. Straight/Curve, which will be released next summer, is about “female body image and the new era of plus size supermodels redefining society’s beauty standards.”

“We have a problem,” begins the trailer. “I know a lot of beautiful women who are size zero and are naturally that way,” says model Leah Kelley. “But to say that that’s the only beauty that should be showcased is not realistic and hurts our society."

Directed by journalist Jenny McQuaile, the Kickstarter-funded documentary goes behind the scenes of New York City’s plus-size modelling industry, following a group of industry professionals turned fashion activists as they fight for diversity and inclusivity .

With female empowerment at its core, the film will try and unpick when, how and why size zero became the norm and size 10 to 14 became "plus-size". A poignant question, particularly when you consider the fact that two-thirds of women fall into this bracket.

“[The documentary] has the possibility to revolutionise the modelling world by challenging a sizeist fashion industry not only to shatter the stigmatising one-size stereotype but embrace the body diversity that exists among all women,” says Kelley in the Kickstarter campaign video.

This isn’t the first time people have challenged the fashion industry’s sizeist beauty standards. Earlier this year Australian model Stefania Ferrario, fed up of being labelled ‘plus-size’, launched the #DropThePlus campaign, and called for the industry to stop using the term to describe women.
