Clothing Size Converter: Korean, US, EU, UK, Japan
Clothing sizes are a mess across countries β Korean 90 is roughly US Small, US Medium is EU 50, and Japanese sizing runs smaller than Western. This converter handles the most common systems for shirts, pants, and outerwear.
There's no global clothing size standard β each region developed its own system based on local body measurements. Even within one system (US 'Medium'), brands vary enormously. Use a converter as a starting point, but always check brand-specific size charts when ordering.
