We're so glad the Jessies fit you well! We do recommend that folks not rely on measuring their feet, as it is difficult to get an accurate measurement of such complex, 3D objects as feet - instead, we recommend you order your regular size in standard-width (or wide width, if ordering from the Wide Collection) heels or women's dress shoes, as we've found that this generally provides better results than attempting to measure your feet.
For international customers, there are usually several shipping options offered. If you select DHL, there is usually a DDU (delivery duties unpaid) and a DDP (delivery duties paid) option, but if you select a USPS Intl option, all of those options will be DDU and customs and taxes will be collected by the customs office in your country.
