Which best describes your ethnicity?

Our ethnic heritages play a major role in determining the shapes of our bodies and we’ve found that by incorporating this information into smart sizes, the algorithms are able to more accurately predict someone’s optimal shirt dimensions.

This answer is only helpful when combined with other answers, and it often only results in minor changes to the predicted shirt dimensions. But those small changes are often the difference between a perfect fit and a not perfect fit.

This question is optional (most are). Please feel free to leave it blank if you’re not comfortable answering, or if you don’t feel any of the options listed accurately describe your ethnicity.

Your answers to all smart size questions are kept confidential, and are only used by Catinat Cloth to calculate your smart size shirt size.
