One handbag shape that I've been pining over but have not voiced or explored is the shopper. Jil Sander made an amazing bag that had the gentle folds of plastic bag, but was crafted in the most exquisite, supple leather. I was looking through the Alexander Wang sale items on ShopBop, and I noticed that he too made a shopper. At $157.50, I just don't know. I think I can do better.
Edit: I wanted to show a pic of the Jil Sander in white, but I could only find it in black. I love black, of course, but in the photo it's more difficult to see how wonderful the leather is.
At Barneys.com for $199--be wary of availability, however.
