According to the designer, the 21-year-old model wasn't 'quite as thin' as the other girls.
Gigi Hadid may be the "It" girl of the modeling world, but according to Tommy Hilfiger, there was a time when she wasn't allowed to show any skin during a runway show.
While speaking with Yahoo! Style, the legendary fashion designer revealed the real reason why he and his team dressed Hadid in an oversized poncho during his Fall 2015 New York Fashion Week show last February.

"Our casting director said, 'She doesn't really fit because, you know, she's not quite as tall as the other girls, she's not quite as thin," Hilfiger explained. "So they put a red, white and blue poncho on her -- it covered a lot of her body unfortunately, but it received millions of hits."
"So I said, you know, why don't we ask her to design a line with us," he continued. "So I said, 'Gigi, come design this with me, we'll do a Gigi x Tommy couture line.'"
Hilfiger later released a statement to ET about his comments to Yahoo, saying that he was "extremely proud" of the young model.
"Gigi is truly the definition of a 'Tommy Girl' -- her magnetic personality is bright, confident and always optimistic," he said. "I've known her for many years, and am extremely proud to have her as the ambassador of my brand and as a collaborator of our collections. Any statement to the contrary is completely false. The headline from the interview with Yahoo was misleading and has since been corrected."
Yahoo's previous headline mentioned that Hadid "wasn't thin enough" to "show skin" during Hilfiger's runway show.
Now, the designer couldn't be happier to work with the 21-year-old California native for breaking down those beauty standards. Not only did he let her flaunt her petite figure in his Spring 2016 show a few months later, but he also kept his promise. Hilfiger collaborated with Hadid -- whom he calls an "All-American girl next door with an exotic twist to her look" -- on an adorably chic nautical collection that made its debut at NYFW in September.
To show off their Tommy X Gigi collection, the two put on a carnival-themed fashion show. ET was backstage with Hilfiger moments before the models rocked the runway, where he simply couldn't contain his excitement over the partnership.

"I can't wait to see all the models in the Gigi collection because these are girls Gigi cast for us, the clothes she designed for us and with us, and we've been working on them for almost a year," he gushed.
