The Idea

Finding plus-size fashion is frustrating: searching through dozens of shops, filters that lead nowhere, results that only go up to L. xl4you was born out of a concrete desire to end that frustration — a platform that aggregates products from all major shops, filtered to XL through 12XL.

The Implementation

xl4you.de aggregates product data from over 10 partner shops: Zalando, About You, Otto, Amazon, Bonprix and more. Search is powered by OpenSearch for real-time filtering by size, brand, colour, and price.

  • Product Pipeline— automated import and normalisation of product data from various shop APIs and feeds
  • Smart Size Filters— normalises different sizing systems (EU, UK, US) into a unified XL–12XL grid
  • Fast Search— OpenSearch-powered with autocomplete, facets, and real-time results
  • Affiliate Model— free for users, monetised through partner links to shops

The Result

A lean, fast search engine that does exactly one thing right: making plus-size fashion findable. No account, no cost, no distractions — pick a size, search, go straight to the shop.
