How Marine Layer Scales Nationwide With Real-Time Store Data

January 12, 2026 · Corinne Suarez, Head of Retail, VP · Joe Shasteen, Global Manager of Advanced Analytics

Marine Layer, the San Francisco-based apparel brand known for its soft shirts and California-inspired collections, has grown from a single store to 57 locations through strategic, data-driven expansion. Corinne Suarez, who leads retail for the brand, joins Joe Shasteen, RetailNext's Global Manager of Advanced Analytics, to explain why Marine Layer chose RetailNext as its intelligence partner and how real-time analytics changed the brand's ability to capitalize on peak shopping moments.

Corinne is candid about the hard parts of scaling out of a home market: replicating a whimsical, slightly snarky culture across new teams, and building awareness in single-store markets where nobody knows the brand's roots. She explains why the neighborhood locations that got Marine Layer here weren't going to get it there, and how traffic and customer-profile analysis supported the shift into larger malls and centers — along with the tourist reach that comes with them. Passerby data opened a second question the brand hadn't been able to answer before: what about everyone who didn't come in, and how do the windows, storefront, and visual merchandising change that?

The conversation also covers Marine Layer's two experiential pop-ups — a colorful Fillmore Street location in San Francisco that became the highest-trafficked store in the fleet in Q4, and a Nolita speakeasy in the basement of the SoHo store — including the KPIs that told them it was working and the staffing decision the in-store conversion data forced within weeks. Learn how emerging brands can use the same enterprise-level intelligence that powers global retailers to scale confidently while protecting the community-driven experience that defines them.

Key takeaways.

  • What got you here won't get you there. Neighborhood stores gave Marine Layer a confined traffic pattern. Traffic and customer-profile data supported the move into larger malls and centers — and the broader, more tourist-driven reach that came with it.
  • Passerby data reframes the question. Instead of only analyzing who came in, passerby cameras let the team quantify who walked past — turning windows, storefront, and in-box visual merchandising into a measurable lever.
  • Test and learn beats big-bet planning. A small, nimble team can pilot quickly and iterate on the metrics. In one case, traffic and customer-profile analysis on two dual-gender stores led to converting one into a men's-only store.
  • Pop-ups are testable, not just brand plays. The Fillmore Street pop-up trafficked highest in the fleet in Q4 on the strength of location, marketing, and in-store experience — chain stitching, 100+ patches, a photo booth, and events.
  • Conversion data drives staffing decisions fast. In-store conversion at Fillmore told the team what was happening in the box; they tripled the size of the team in a very short window.
  • Match the KPI to the concept. Traffic, in-store conversion, average dollar sale, and UPT each answered a different question about a customization-led experience — and exposed the technology work needed to support it.
  • The 2026 roadmap is experience-led. More pop-ups, continued renovations and relocations across roughly a third of the fleet, and a first move into outlets — with the same test-and-learn analytics discipline applied.
