you can rebuild
- Modal-based interactive step-by-step body measurement questionnaire.
- Mathematical matching algorithm comparing user dimensions to garment specs.
- Shopify storefront widget injection script and LocalStorage profile persistence.
- Basic admin portal for manual size chart JSON/CSV uploads.
- Fit preference adjustment sliders (Tight vs. Loose fit bias).
what you lose
- Pre-mapped sizing databases for thousands of major fashion brands and suppliers.
- Machine learning fit algorithms refined by millions of historical return/conversion data points.
- Turnkey integrations with major e-commerce platforms and headless storefront framework adapters.
- Automated onboarding tools that digest merchant size tables without manual developer intervention.
real moats
- Historical cross-brand fitting datasets mapping real consumer return rates to specific garment measurement patterns.
- Proprietary database of standardized size charts covering tens of thousands of global fashion items.
