I am thinking about getting a new bag and the Retiro PM has caught my attention. I previously had a Palermo PM and sold it (I fell out of love with it). Is the Retiro PM too similar to the Palermo PM?? What are the pros and cons of the Retiro PM?? Any help is appreciated!!! (FYI my current collection includes the Speedy B35 (Ebene), Totally MM (Mono), Delightful MM (Mono) and Noe (Mono).
