Frequently asked questions
- Is Japanese clothing smaller than US clothing?
- Often yes for the same letter label. Japanese cuts also tend to be slimmer, so body measurements are more reliable than letters alone.
- Should I trust this table over a brand size chart?
- No. This page is a generic planning reference. Always use the brand official chart when it is available.
