I'm sure this has been asked before, but I cannot find a solid answer anywhere. Which designer originally made the over-sized zipper-pull bag? I know Chloe made the big lock bag, but I've heard mixed information about the large zipper. I really like the look for the big zipper, but I am not willing to buy a fake, and that's a little hard to do when you don't know made it in the first place! Thanks!
