I picked up a medium in midnight at Sien in Antwerp on Friday. They had many of the colors and sizes, including a small size that is not available at
Barneys. They had small, medium, and large in the style with a shoulder strap, and the small pochette. The python in person was stunning. It's rubberized python, so the scales don't lift up like other python. I am thinking of getting the small version in python next time I go back, if the Euro stays low against the dollar of course!
If you are traveling to Europe I recommend going to the Sien boutique in Antwerp for this bag since they are the first to have it for sale in Europe. They said Harrod's would have it in London and I think Printemps in Paris, but it is fairly exclusive at the moment. I feel like I got a bargain because the price in Euro was less than the retail price in USD, plus I got VAT back and didn't have to pay US sales tax. And the leather and styling is gorgeous.
