International Clothing Size Converter & Chart

Direct Answer Summary

International clothing sizing varies significantly across regional fashion markets. A US women's size 6 translates to a UK 10, French EU 38, Italian 42, and Japanese size 9. When purchasing overseas garments, using anatomical body circumference in centimeters provides the most reliable fit across differing international grading rules.

Common Questions

Frequently Asked Questions.

Expert answers regarding apparel fit, garment dimensions, and international fashion sizing.

What is a US Women's size Small (S) internationally?

US Small (sizes 4-6) corresponds to UK 8-10, EU 36-38, Italian 40-42, and Japanese sizes 7-9.

Why do Italian clothing sizes look so large numerically?

Italian sizing is based on half the total chest/bust circumference in centimeters, leading to labels like 40, 42, 44, and 46.

What is the best way to avoid sizing errors when ordering clothes abroad?

Always consult the brand's metric centimeter chart for bust, waist, and hip measurements rather than relying solely on regional numeric tags.
