Inside the Fashion Cosmos - Where brands, technology, and ideas meet.

For a growing share of shoppers, resale is now the first point of contact with a luxury brand. NYU Stern Professor Thomai Serdari explains what that means for the companies behind the labels.

Together with host Liz Alessi, she walks through Resale Revalued, a new study built on research by her MBA students, and why so many brands still hesitate to engage with secondhand: technology designed only for new goods, the risk of authentication errors, and no clear owner inside the organization.

The conversation also covers what the gap between retail and resale prices reveals about brand perception, why watches and jewelry offer a clear view of pricing power, and how AI shopping agents could turn resale into an acquisition channel.

Made for executives whose resale strategy sits somewhere between merchandising, sustainability, and e-commerce.

The takeaway: the market has already decided that secondhand matters. What remains open is who owns the data that explains why.
