How Do I Use Specific Size Charts?
Our handy size conversion charts shows you which size to select based on your established size for each particular brand. Since sizing may vary by different brands or collections, be sure to keep a lookout! An international size XS in one brand may be equivalent to EUR 36 while international size XS in another brand may be equivalent to EUR 34.
For example, if you regularly fit into EU 36 then the equivalent international sizing for this dress from Na-Kd is XS.
You may choose XS for this particular dress but it may not be the case for other brand/s items.
Make sure to pay attention to the size chart and the product info of each item.
