Back in May 2015, H&M announced a designer collaboration with Balmain.
This week, Instagram user Kathryn Swartz Rees found 99 photos from the collection, set to debut Nov. 5, and posted them on her account.
Swartz Rees told BuzzFeed Life, "While searching for editorial images of the collection (being a month out, the timing was right) I came across a Google search result from H&M's domain with an abnormal page title."
A representative from H&M told BuzzFeed Life, "Images from our Balmain x H&M collaboration have surfaced. We are pleasantly surprised by our fans positive reaction to the collection."
UPDATE
Since this story was originally published, Kathryn Swartz Rees's account has been disabled by Instagram.
Another Instagram account, @Balmainxhm, has posted a majority of the photos to its page.
