Nearly everyone in fashion is using AI now. Hardly anyone trusts it with the big calls. That gap is the most useful lens for reading any AI trend forecast in 2026. In the space of two days, The Interline published two pieces from its new AI Report 2026 that point at the same tension. A survey for the report found that roughly nine in ten fashion professionals use AI every day, but only about a quarter trust its output enough to base important decisions on it. In a separate essay, WGSN chief executive Carla Buzasi argued that AI makes trend forecasting faster but can’t do the part that matters most: telling a passing spike from a lasting shift.
The Trust Gap, in Numbers
The headline figures come from The Interline’s AI Report 2026, which drew on around 100 survey respondents across different levels of the industry. The sample is small, so treat the exact percentages as a snapshot rather than a census. Still, the shape is striking: AI has become routine at work, yet most people using it every day still check its answers before acting on them.
Speaking on The Interline’s podcast, Rupert Schiessl, chief strategy and AI officer at sourcing and product-lifecycle software company Bamboo Rose, offered a practical reason for the gap. People trust what they can check, he argued, and a bare confidence score doesn’t give them anything to check. “Providing a chain you can check is much more convincing than a confidence score,” he said. The report also suggests the industry sees AI as most mature in concept development and marketing, and least trustworthy in technical design, sourcing and production, where a wrong answer costs real money.
Trend forecasting sits awkwardly between those two groups. A forecast feels creative, but it drives very concrete buying decisions: how many units, in which colors, landing when.
What a Forecaster Says AI Can’t Do
Buzasi’s essay makes the case from the vendor side, so read it with that in mind: WGSN sells human expertise alongside its AI products. Her core argument is still worth taking seriously. Social platforms produce endless micro-trends, and in her words, “for every emerging behaviour on TikTok that becomes a product shift, there are a hundred that flame out in three weeks.” Spotting what’s viral is easy. Knowing what will still sell next season is the hard part.
She also argues that the earliest signals show up in real life before they show up in any dataset, which is why WGSN describes its network of more than 250 trend experts as the “input layer” of its AI systems rather than an add-on. Then comes the step she calls craft: turning a trend into a product that actually works, which depends on people who know how a fabric behaves after fifty washes.
What changes, in her telling, is speed and access. Forecasts that used to arrive as reports and slide decks now live as structured data that a merchandiser can query directly and get an answer in seconds. That matches what we saw last month when WGSN opened up its runway AI data to clients. Buzasi says those answers are grounded in “25 years of forecast accuracy.” Neither piece explains how that accuracy is measured, and that’s still the question buyers should be asking.
How to Read an AI Trend Forecast
Put the two pieces together and you get a fair working rule for 2026: use AI trend forecasting to see more signals, faster, and keep a person accountable for which ones you act on. Before you lean on any AI forecast, whether it comes from a big subscription service or a free tool, ask three things:
- Where did the signal come from? Runway tagging, social posts, search data and sales data tell you very different things. A forecast that can’t show its sources is the confidence-score problem Schiessl describes.
- How long has it lasted? A spike that’s a few weeks old is exactly the kind Buzasi warns about. Look for signs that it’s persisting across markets or seasons.
- Can it be made and sold? A trend that holds up on social media can still fail on cost, fit or fabric. That’s still a human call.
The takeaway isn’t that AI forecasts are unreliable. It’s that the industry hasn’t settled how to check them yet, and the people using them most are, sensibly, still checking.
FAQ
How many fashion professionals trust AI for important decisions?
According to The Interline’s AI Report 2026, roughly nine in ten fashion professionals surveyed use AI daily, but only about a quarter trust its output enough to base important decisions on it. The survey had around 100 respondents.
Can AI predict fashion trends on its own?
AI is good at spotting patterns across huge volumes of runway, social and search data. Forecasters like WGSN argue it still needs human experts to catch early real-world signals, separate lasting trends from short-lived viral moments, and judge whether a trend can become a product that sells.
What should I look for in an AI trend forecast?
Check where the data came from, how long the trend has persisted, and whether the forecast explains its reasoning rather than just giving a score. Forecasts that show their working are easier to trust and easier to challenge.
