I love doctor bags. They are roomy, and the kiss clasp is simple irresistible.
This one is Balenciaga, it's name is Partition. I dare say it won't be the "It" bag of next season. I might be wrong, but celebrities don't like this kind of bags. Beyond perfect!
I am pretty sure, I won't collect all the money I need to buy it, but I will try to find something similar in vintage stores.
Update: there are two sizes, the small one is 1275 euro and the large one is 1375 euro. The leather is the same one as in the motorcycle line.
