Body measurements travel better than labels
Bust or chest, waist, hip, and sometimes height are more useful across countries than a single S/M/L or numbered label. Use the garment category that matches the item.
International conversion is approximate
US, UK, EU, and other clothing labels are conventions rather than one synchronized system. Use conversion tables to narrow options, then check the seller’s measurement chart.
Use the body dimensions that control the garment
Use body measurements first and international labels second; country labels are not universal standards. For tops and jackets, chest or bust may dominate; for trousers, waist and hip may matter more.
International labels are only nearby references. The measurement row and product chart should decide the final size.

How this guidance is checked
These sources support the measurement method and help check real-world variation. They are not presented as one universal brand-size table.
- ISO 8559-2:2025 — Size designation of clothes — Primary and secondary dimension indicators — International Organization for Standardization (ISO). Clothing methodology: size designation should be based on defined body measurements rather than assuming universal retail labels.
- ISO 8559-3:2018 — Methodology for body measurement tables and intervals — International Organization for Standardization (ISO). Clothing methodology: body measurement tables are population- and interval-based rather than one universal brand-independent chart.
- Ladies Size Guide — H&M. Cross-check for women’s US/UK/EU clothing labels and bust, waist, and hip body measurements.
- Women's Clothing and Underwear Size Charts — Calvin Klein. Second-brand cross-check for women’s pants, dresses, outerwear, and the variation in numeric sizes at similar body measurements.
