I've been debating on jumping into the Balenciaga craze, but have been discouraged about the leather fading. I take fairly good care of my bags, but I don't want to buy one that I'm going to have look after frantically while I'm using it. I've read about owners covering their bags while driving and having the bag in the passenger seat. So how easy and fast does a Balenciaga to fade? I'm looking in to a Raisin, Charcoal, or Black City bag. Any advice would be appreciated!
