I just purchased the parchment w/chocolate leather large Carly. I lOVE it but I'm nervous to keep it after I found out the light colored leather is Vachetta. I'm scared it will be hard to keep clean and I'm nervous about what color it will patina....I'm just learning about Vachetta leather. Anyone own this bag and have regrets? How has this bag held up for those that own it? To keep or not to keep...thanks for your advise!
