Tim Gunn called out the fashion industry for ignoring plus-size women in an editorial he wrote for The Washington Post this week.

The Project Runway co-host said that the majority of American women are unlikely to receive much attention at New York Fashion Week, which started on Thursday, and he says it's a big issue in the industry.

"I love the American fashion industry, but it has a lot of problems, and one of them is the baffling way it has turned its back on plus-size women," Gunn said. "The average American woman now wears between a size 16 and a size 18."

Gunn said that for the past three years, plus-size women have increased their spending on clothes faster than their straight-size counterparts.

"There is money to be made here," he said. "But many designers — dripping with disdain, lacking imagination or simply too cowardly to take a risk — still refuse to make clothes for them."

The design educator admitted that the problem has even extended to Project Runway, which has a "real women" challenge every season that he says makes the designers "audibly groan."

He pointed out that things changed this past season when Ashley Nell Tipton won the competition with the show's first plus-size collection, but he said it was far from the fix he's been looking for.

"Even this achievement managed to come off as condescending," Gunn said about Tipton's win. "I’ve never seen such hideous clothes in my life."

He went on to say that her "victory reeked of tokenism" and that a judge told him that she was "voting for the symbol" that the clothes represented for a "certain population."

"I said they should be clothes all women want to wear," he responded. "I wouldn’t dream of letting any woman, whether she’s a size 6 or a 16, wear them. A nod toward inclusiveness is not enough."

Gunn said change is not impossible, but it is up to designers to "make it work."
