The images, which weren't supposed to be released until October 19, were posted by Kathryn Swartz Rees, a Chicago-based writer and editor, who supposedly stumbled upon the images by mistake.
Kathryn told The Cut, "The real story is terribly unexciting: H&M's site was indexed by Google and I happened to search at the right time using the right parameters. All images were taken from that H&M URL. No surprise, the site is no longer live."
The images showed that the collab was indeed everything we'd been hoping for and include designer Oliver Rousting's best-known looks for the house: plenty of gorgeous baroque-esque beading and studded details, sharp tailoring and yes, that killer jacket Kendall Jenner debuted at the Billboard Music Awards this year.
Unfortunately, Kathryn has since removed the images from her Instagram, saying in a recent post that H&M had requested she take them down.
While we're pretty bummed we can't drool over the to-die-for looks and plan our wishlists, the leak has made us even more excited for the collection to finally be released on November 5. Get your running shoes ready fashionistas, because by the looks of it, you're going to have to move quickly on November 5 if you want in on this one!
