When a fashion brand enters a new market, there are many things to adapt: the language, the channels, the marketing. But there is one that is often overlooked until problems arise: sizing. What fits well in one market can generate twice as many returns in another if no one has considered how to communicate it properly.
Naiz Internationalisation solves this problem systematically. It unifies the brand’s sizing logic, defines market-specific rules, and ensures that the sizing experience is consistent and easy for the shopper to understand, regardless of the country they buy from.
The system operates in three layers: first, it establishes a unified size structure for the entire brand; then it applies each market’s specific rules on top of that base; and finally, it integrates that logic consistently across all channels where the brand operates.
It establishes a common, consistent size structure for the entire brand, regardless of market or channel. Instead of manually managing separate size charts by country in an uncoordinated way, the Unified Sizing System creates a single foundation from which all regional adaptations are derived.
Each market has its own sizing conventions: different names, different numeric scales, and fit expectations that vary by culture and by the morphology of the local population. Market-specific Rules makes it possible to define each region’s specifics on the unified base, so that shoppers in each market see a familiar, easy-to-understand size reference.
It integrates cross-border sizing logic into the brand’s systems and channels: ecommerce, retail, and size recommendation tools. When a shopper browses from another country, or when a brand sells in multiple markets from a single platform, Cross-border Integration ensures that size conversions are correct and that the experience does not create confusion.
Entering a new market with a size chart designed for another market is one of the most common causes of returns in international expansion. Naiz Internationalisation removes that friction before it becomes an operational and reputational issue.
A brand that sells in six markets and manages sizing differently in each one ends up with a fragmented experience that customers notice. Naiz Internationalisation ensures that sizing logic is consistent from ecommerce to physical retail, across all markets and in all languages.
Without a structured system, each new market entry means redefining the sizing strategy from scratch. With Naiz Internationalisation, the foundation is built, and scaling to a new market means adding its specific rules on top of a structure that already works.
Manually managing size conversions between markets, keeping country-specific charts up to date, and coordinating that information across teams takes a lot of time and leads to errors. Naiz Internationalisation centralises and automates that management.
A solution that helps fashion brands manage sizing complexity in international markets. It unifies the brand’s sizing structure, defines region-specific rules, and integrates them consistently across all channels, so that shoppers in any market understand sizing and can choose with confidence.
Because sizing systems are not standardised globally. Conventions vary between countries, size names differ, numeric scales do not match, and shoppers’ fit expectations differ by market. A brand that does not adapt its sizing communication to each region creates confusion, which translates directly into more returns and lower conversion.
Yes, and it is often in that context that it delivers the most value. Brands that already operate in multiple markets but manage sizing in a fragmented way can use Naiz Internationalisation to organise and centralise that strategy without having to start from scratch.
Yes. The sizing logic defined by Naiz Internationalisation integrates directly with Naiz Size Advisor and the rest of the platform’s solutions. This ensures that the recommendations shoppers receive in each market are aligned with their region’s rules and conventions.
Ideally, it should be implemented before entering a new market, as part of preparing the sizing strategy for that region. However, it also makes sense for brands that already operate in multiple markets and identify sizing consistency issues or return rates higher than expected.
