Craig Brommers, American Eagle's CEO, called the campaign ”a very successful campaign for us.“ Anu Lingala, citing Tracksuit data, said it ”severely damaged American Eagle Outfitters Inc. brand health amongst its core customers.“
Both of them are looking at real numbers. Neither one is lying. That's the bigger problem, not the smaller one.
Rob Meyerson, the brand strategist whose naming work I've drafted off of for years, posted a question that started this: was the campaign a massive success or an unmitigated disaster? I run brand momentum data for a living, so I told him I'd go check.
Here's what I found. Everyone was measuring how loud the room got. Almost nobody was checking who was making the noise.
Rob made the point using the dress. You remember it: half the internet saw white and gold, half saw blue and black (which was correct, confirmed by the manufacturer), and both sides were dead certain the other side was either lying or color blind. Same photo. Same light. Two irreconcilable readings, and nobody was wrong about what they saw.
That's Brommers and Lingala. A loud cheer and a loud boo register the exact same decibel level on a meter that only measures volume. Impressions, mentions, search spikes, follower counts: they'll tell you the room got loud. They won't tell you whether the crowd is walking toward you or away from you.
After a slight political discussion over it, YouGov clocked brand impression moving +13 among Republicans and -16 among Democrats in the same three weeks. Average that out and you get "slightly positive," which is the statistical equivalent of calling a room "comfortable" when half of it is on fire and half of it is in a walk-in freezer. That's how a CMO and a brand tracker end up describing two different companies without either one making anything up.
So instead of picking a side, I ran thirteen months of American Eagle through our Brand Momentum Score™. It scores three things, using public signals only: Attention, are people noticing you; Animation, are they actually moved to act; Amplification, are they telling their friends.
The peak of momentum, generated by the campaign, came the month after launch
Before the campaign, July 2025: 42. Post-launch peak, August 2025: 74. Now, August 2026: 52. The campaign generated 32 distinct moments of momentum. Nine are still alive thirteen months later.
And while that's something, the real story is hiding inside the peak.
At the August peak, Amplification hit 92. About as high as this metric goes. People were sharing this campaign like it owed them money.
Animation, the number that measures whether people were actually moved to act, sat at 48 in that same exact month.
You can watch the gap play out in the behavior. Site traffic rose 60%. Cart conversion moved 0.08 of a point, basically lost in a rounding error. Yet, store foot traffic fell nearly 9% in the worst week and closed August negative, while competitor Gap ran positive off the KATSEYE campaign in the same window.
What American Eagle did was build a reservoir of cultural energy that just never went anywhere. The hero jean sold out in a day, and everyone read that as proof of demand, but it wasn't. It was merely a limited stock supply ceiling. Two very different problems, and only one of them means you're winning.
On the other side, Aerie by AEO, Inc., American Eagle's sister brand, ran no celebrity and no controversy over the same fourteen months. Their momentum score went from 47 to 68. It crossed American Eagle in momentum points by January 2026 and never looked back, then posted +25% comps in the same quarter American Eagle posted -2%.
Aerie crossed AE's momentum by January 2026 with no celebrity and no controversy
Same parent company. Same economy. Same tariffs. Same consumer with the same wallet. The momentum was real. It just picked a different sibling to live with, and you'd never know that if you stopped at the top-line number of corporate AE alone.
Then there's the re-up. Yes, American Eagle kept Sydney Sweeney for the next round. But in May they told investors that back-half spend was shifting toward performance marketing, influencers, and day-to-day traffic drivers. Keep the famous face out front, quietly move the money somewhere else. You don’t do that when the thing it's doing is unambiguously working. Revealed preference beats the press release. Budget cycles and inventory realities move for reasons that have nothing to do with one campaign.
Attention is something you get. Momentum is something you convert.
The finding: Attention is something you get. Momentum is something you convert. This is bigger than ”did the jean ad work.“ American Eagle in fact did get attention. It got an enormous amount, historically well, and I'd defend that number to anyone. What it failed to do was convert it, in the exact category the campaign was built to sell.
Momentum can leak. You can generate real cultural energy and lose most of it between the moment and the merchandising, because the product, the customer experience, or the next three moves on the calendar weren't built to catch what the campaign threw at them.
That's the question worth asking a CMO instead of ”was this good or bad.” When the moment hits, is the rest of your business built to receive it, or does it hit the floor and roll under the couch?
One back at you, Rob. Every executive team walks into that boardroom holding a number. Impressions, sentiment, momentum, pick one. Only one of them is still going to be true in six months.
