When the platform is the bottleneck
Campaigns moved at the speed of someone else's backlog. Two brands, ten markets, and a fashion calendar that doesn't pause for tickets. The architecture was the bottleneck.
American Eagle
Two brands, one platform, complete ownership.
American Eagle has been making jeans for Americans since 1977. Along the way it has become something more: a casual-apparel mainstay built around denim, basics, and a relaxed Pittsburgh sensibility. Its sister brand Aerie launched in 2006 and turned an intimates line into a body-positive lifestyle brand that resonated far beyond its original category. In Europe, the two brands share a customer, a calendar, and an operating team. Each carries its own visual identity, voice, and product universe.
Running both of those identities through one platform is the puzzle that brought American Eagle to Ask Phill.

"Ask Phill helped us migrate to Shopify in a structured and reliable way, giving us full ownership and the flexibility to scale our ecommerce setup."

One theme, two brands
The brand detector and selector snippets make the whole thing self-aware: drop a customer onto the storefront and the experience knows which world they're in.
By the numbers
Iteration speed is no longer gated by external support. Commercial and UX improvements that previously took weeks now move at the speed of the in-house team.
What's next.
Size chart improvements per country, and an extended discounts scope to handle more nuanced promotional logic across markets. The platform is set up to keep moving.
American Eagle
Migrating American Eagle Europe onto a single Shopify Plus theme that powers both American Eagle and Aerie.
When the platform is the bottleneck
American Eagle Europe was running on a managed custom platform that handled the basics but left the team without the levers a modern retail operation needs. Changes to the storefront required external support. Campaigns moved at the speed of someone else's backlog. Two brands, ten markets, and a fashion calendar that doesn't pause for tickets. The architecture was the bottleneck.
The brief: migrate to Shopify Plus, bring both brands onto a single platform, and do it without the operational shock that usually accompanies a cross-platform move during a live retail season.
One theme, two brands
We started with a foundational call. Stay on Shopify-native rather than going headless. Headless gives flexibility but adds complexity that wasn't necessary here. The European team needed speed, autonomy, and a setup their merchandisers could operate without going through engineering for every change. Shopify native, combined with the Ask Phill Accelerator (APA) base theme, delivered that.
The harder call sat one layer up. American Eagle and Aerie could have been two separate themes, two deployments, two maintenance tracks. We went the other way: a single theme handling both brands, with brand detection and a brand selector built into the code. Navigation, homepages, and block styling all read the active brand and render accordingly. The team works in one place, and updates roll out to both brands at once.
Shopify Markets with per-context templates, five languages (English, Dutch, French, German, Spanish), and three currencies (Euro, GBP, Swiss franc). Content management lives in native Shopify: metaobjects, theme sections, and blocks. Search runs on Shopify's native and predictive search. Payments run on Shopify Payments. No external CMS, no auxiliary search vendor, no extra payment gateway adds latency between idea and live page.
The custom layer is where the multi-brand logic shows up. We built a brand-aware megamenu for desktop and mobile that reorganises itself depending on which brand the visitor is in. We built variant swatches tuned to each brand's product structure, and product promos that key off campaign metadata. The brand detector and selector snippets make the whole thing self-aware: drop a customer onto the storefront and the experience knows which world they're in.
A critical part of the decision: the store stays in sync with the APA base theme. Updates to the Accelerator roll downstream. Two retail brands running on one Shopify theme, still receiving Accelerator updates, was not something we had built at this scale before this project. Marketing tooling sits alongside through Klaviyo, with multi-list newsletter subscription wired into the storefront.

Kickoff sat in the final week of 2025. Ask Phill delivery ran four months, January through April. The site went live on 19 May, with the cutover happening at midnight Amsterdam time. American Eagle's team connected the domains, tested the live environment, and went live themselves. By the time the cutover came around, the preparation had already done the work, and Ask Phill didn't need to be on call. More than 2,500 redirects routed legacy URLs into the new structure with no major issues reported.
Beyond the migration mechanics, the European team came out of the project with full ownership of their storefront. Iteration speed is no longer gated by external support. Commercial and UX improvements that previously took weeks now move at the speed of the in-house team.
