BackThe Sadie Sink Calvin Klein Deepfakes, Explained
AI-generated underwear photos are styled to look like Sadie Sink's real Calvin Klein campaign. Here is what AI or Not detected.
By now you've probably scrolled past Sadie Sink in Calvin Klein denim. The '90s Straight Jean, the Low Rise Baggy, an indigo wash she called her favorite look. Calvin Klein published the second chapter of its Fall 2026 "Feel the Fit" campaign on September 1, shot by Aidan Zamiri, and every frame of it is about jeans, and real.
You may also have scrolled past Sadie Sink in Calvin Klein underwear, standing in a kitchen with a white mug, in a second kitchen with a green one, in a sunlit bedroom, and in a walk-in closet holding a black t-shirt.
None of those images are from the campaign. They're fake, built to look like a shoot that never happened. Two days after the real ads went live, AI or Not's incident tracker caught all the AI images.
The Real Calvin Klein Campaign Sadie Sink Actually Shot
"Feel the Fit" is Calvin Klein's Fall 2026 denim push. Sadie Sink, who plays Max Mayfield in Stranger Things and Jean Grey in this summer's Spider-Man: Brand New Day, told W Magazine she was flattered Calvin Klein asked her to front the campaign, calling it "such an iconic brand."
"The dark indigo, denim-on-denim look. That was my favorite because there was something really tough about it, but it also felt flattering and fitted."
The real shoot is denim, the AI one is underwear.

What AI or Not's Detector Found in the Fake Calvin Klein Images
How the Sadie Sink Calvin Klein Deepfakes Were Made
Nobody needs a studio for this anymore. Openly available image generators can be fine-tuned on a few dozen photos of one face and produce a new scene in minutes, skipping the photographer, the wardrobe, and any need for the subject's consent.
If a major generator refuses the request, no problem, as plenty of open source alternatives exist. And they are almost as good and have zero safeguards to prevent someone from creating images like this.
Brand Impersonation Is the Part Nobody Is Tracking
Most stories about celebrity deepfakes focus on one harm, a face used without consent. That's real, and current law is built around it. These images carry a second harm that barely gets mentioned. A company's name and product line got stitched onto photos it never made and never authorized.
Calvin Klein sells both jeans and underwear, which is exactly why a fake underwear photo doesn't look obviously wrong. Real Calvin Klein underwear campaigns exist, which is exactly what these photos are borrowing from. The one Sink actually fronts is denim. Calvin Klein hasn't commented on the images, and nothing indicates the company's own channels distributed any of them (or is even aware of them).
A March 2026 investigation into deepfakes of Sink and her Stranger Things co-star Millie Bobby Brown turned up eleven images flagged the same way, months before this batch. This list has been growing since June. Calvin Klein is just the latest addition to it.
What the Law Covers and What It Misses
The TAKE IT DOWN Act, signed in May 2025, makes it a crime to publish an intimate image posted without consent, AI-generated images included, and requires platforms to remove one within 48 hours of a valid notice. The FTC began enforcing that notice-and-removal provision in May 2026.
The DEFIANCE Act, which passed the Senate unanimously in January 2026 and is still pending in the House, would go further: a civil claim in federal court, with statutory damages starting at $150,000, rising to $250,000 when the deepfake is tied to sexual assault or stalking.
Neither law was written with these images in mind. The deeper injury runs to Calvin Klein's trademark, and neither statute compensates that kind of harm. A person defamed by counterfeit images has a law to invoke. Calvin Klein doesn't have one.
How to Spot a Fake Celebrity Ad Campaign
- Check the brand's channels and press materials. A real campaign names a photographer and sells a specific product.
- Watch for a setting mismatch, like underwear turning up in what's supposed to be a denim campaign.
- Do two images look like the same shoot, rerun with one prop swapped? Generators make near-duplicates easily; photographers rarely bother.
- Run the image through AI or Not instead of trusting a scroll-speed glance.
Sadie Sink Deepfake FAQ
Are the Sadie Sink Calvin Klein underwear photos real?
No. Calvin Klein's real Fall 2026 campaign with Sadie Sink is all denim. AI or Not flagged all Sadie Sink underwear images as AI-generated.
What is Sadie Sink's actual Calvin Klein campaign?
It's chapter two of Calvin Klein's "Feel the Fit" Fall 2026 denim campaign, shot and directed by Aidan Zamiri and published September 1, 2026, across three denim styles.
How can you tell if a celebrity ad campaign image is AI-generated?
Check the brand's press materials; a real campaign names a photographer and a product. Look for near-duplicate images with a swapped prop, a sign of a generated batch, and run the image through AI or Not to double check.
Is it illegal to make deepfakes of a celebrity in a brand's clothing?
The TAKE IT DOWN Act covers intimate images posted without consent, but a suggestive image that isn't sexually explicit can fall outside that definition. The pending DEFIANCE Act would add civil damages for victims, but neither law clearly addresses harm to the brand whose trademark was used without permission.
