If you want to know what's actually going to matter next season, stop reading trend reports and open Depop. The resale market has no agenda. It has no advertiser relationships, no designer access to protect, no reason to tell you something is trending if it isn't moving. When a Chanel ballet flat sells for three times retail two weeks after the show, that's a real signal. When a specific silhouette starts appearing in hundreds of new listings at a premium, something is happening that no runway review can manufacture.

Vogue tells you what the industry wants you to want. Depop tells you what people actually went home and searched for after the show. Those two things are not always the same, and the gap between them is where the most interesting forecasting lives.

The reason nobody talks about resale velocity as a forecasting tool is that it's harder to package into a trend report and it doesn't make designers feel good. But it's more honest than almost anything else we have, and eventually the industry will catch up to what the data already knows.

We're building it into our scoring model. Watch this space.
