This Fall's hottest shade of Grey is available online at Mytheresa.com. Luckily for Bow Bag lovers that's exactly the style available in Argilla. Buy here for 960 euro.
By the way, I highly recommend Mytheresa.com. I have bought Miu Miu from them in the past and have not had a problem. They ship outside Europe and since I live in America I was able to get the bag without the VAT.
