I want to get a Fendi B Bag. I just don't know which one. Should I get the all leather? Should I get the canvass with the patent? I keep going back and forth between leather and canvass. I'm trying to figure out which one is the bettwe investment (aside from being really really good looking when I'm carrying it!) All I know is that I love the B Bags that have a contrasting trim and seem to be attracted to the patent trims especially. Suggestions??
