My DH's aunt gifted me my first Prada bag, a saffiano mini crossbody. It's a cute bag but soooo small and not very practical for me. I like my bags big. Do you ladies know if there's any way to exchange it at a Prada store or a department store that sells Prada? I was thinking a wallet or SLG would be more suited for me. She bought it in Milan and I live in LA. The authenticity card has the store name and date of purchase. Thanks for your help!
