Does anyone know if you can exchange a Miu Miu handbag for a Prada at the boutique? I know they are both technically under the same design house of Prada, but are they considered completely different? I know Prada employees can use their discount at both Prada and Miu Miu and vice versa. The only reason I ask is because I received a Miu Miu handbag as a gift and would rather have a Prada instead. Thanks in advance!
