I've YOOX three times now, and have been very satisfied with the products and service both times. Delivery is direct from Italy, and incredibly quick, considerably quicker than Bluefly's standard shipping option, actually. The sizes listed for the Prada shoes seem to be the Prada rather than standard US sizes, and correspond more properly to the British sizing system (essentially British size +1 = American size). Thus the large number of Prada shoes with the description "large sized" in their catalogue. I also find that the translation between European and American sizes is often a little off, even by the manufacturer's estimation (e.g. some manufacturers claim that a 43 is a US 9.5, some that it is a 10.) It is better to know your European size.
