Emily Ratajkowski.

Earlier this summer, Emily Ratajkowski had a problem: She could not stop Instagramming her bikini-filled vacation. About a week after she left Italy, though, Ratajkowski made it clear she'd sorted things out: In a 24-hour period, she posted three photos of herself decked out in head-to-toe denim, the heat apparently forgotten. It wasn't a phase: a week later, she posted another, proving her dedication to the denim craze was true. (And what we all already knew in our hearts: that if anyone can turn a jean jacket into a sleeveless top and still make it work, it's Ratajkowski.)

The last in her series of grams featured Ratajkowski alongside Virgil Abloh, the designer behind Off-White, who earlier in the year sent a model down the runway at his denim-heavy show in a shirt so sheer, she appeared to be wearing only a jean skirt. He's hardly the only designer lately to jump fully on the denim train: Thanks in large part to the newly Americana-crazed Raf Simons, the Canadian tuxedo, of all things, somehow beat out all the other lightweight possibilities in the world to become the ultimate cool uniform this summer. (Conveniently, it also promises to be one that continues into fall, thanks to designers like Dior's Maria Grazia Chiuri.)

As Ratajkowski, Kylie Jenner, and the Hadids can attest, double denim has come a long way since that time in 2001 that Britney Spears and Justin Timberlake both showed up to the American Music Awards in head-to-toe jeans—a moment that this summer, by the way, the brand Filles a Papa commemorated on a $150 t-shirt. Historically, head-to-toe denim has been unacceptable, from when the term "Canadian tuxedo" was first invented: As the story goes, back in 1951, Bing Crosby and his friends's all-denim outfits managed to turned even the Canadians unfriendly, when staffers at a hotel in Canada saw their ensembles and initially denied them entry.

These days, though, Gigi Hadid not only wears the look on the street, but on magazine covers, and Jenner lets her denim belt hang so low, it almost leaves a denim trail behind her on the ground. Beyoncé even rocked the look while pregnant with Rumi and Sir, while names as small as the underground designer Matthew Adams Dolan have found fame since Rihanna started wearing his characteristically denim-heavy designs.

Altogether, their combined efforts have somehow made jorts even more controversial than the Canadian tuxedo. These days, if you're looking to stir things up, you're much better off rocking Vetements's scandalous butt cheek-exposing jeans—just make sure you take Kate Moss's advice, and pair them with denim on top, too.
