Hi Johny,
Your bag is looking fine except it is slightly worn from where you pick it. For that you can simply replace it from Prada. Some stores offer the total replacements if something happens. Let me know where you are residing so that i can tell you where you can replace it. Or if you want to buy a new bag, Di Lusso, Gucci are some of the brands to go for. You can also checkout a new brand in town named Borlino. But is ships only in United States as per my knowledge.
