“As consumer expectations evolve and AI opens up new possibilities for retail, J.Crew is challenging the traditional model of online shopping, moving beyond individual product searches toward a more connected and inspiration-led experience,” said Libby Wadle, CEO of J.Crew Group. “For a long time, we’ve been thinking about how customers will want to shop in the future, and how we can lead that evolution rather than react to it.”

According to Anthropic, J.Crew’s own product team created Style Advisor using the Claude Fable 5.1 model, which Anthropic markets for “complex, open-ended work.” Ultimately, Style Advisor is meant to offer recommendations in ways that a J. Crew stylist would when responding to a customer. J. Crew’s team first made a prototype using Claude Code and Claude Opus 5.5. Their engineers then used that prototype to take the assistant the rest of the way into production.

“We see an opportunity to fundamentally rethink the shopping experience,” said Wadle. “Through our work with Anthropic, we’re bringing decades of J.Crew styling, merchandising and creative expertise together to help shape what’s next for customer behavior.”

How J. Crew’s Style Advisor works

Style Advisor is currently accessible on the JCrew.com site, from a menu option that brings the assistant up within a web browser. There, it displays a user interface with suggested prompts for shoppers.

The Claude Sonnet 5.5 model receives prompts and returns styling-focused feedback. Meanwhile, the Claude Haiku 5.5 model picks up work for shorter, more focused tasks. J.Crew maintains that since the styles being referenced all come from its human team, the recommendations are designed to stay consistent with the brand’s priorities.

“J.Crew has one of the most recognizable points of view in fashion, and its team used Claude to bring that expertise to customers in a new way,” said Paul Smith, chief commercial officer at Anthropic. “They used a frontier model to build the experience and faster, more efficient models to run it, so customers get quick answers that stay true to the brand’s styling.”
