I wanated a Cabas Mezzo for a long time and then a while back I read on here that it was no longer going to be sold. I fortunately was able to snatch one up! Now I'm worried about the bottom of the bag getting dirty. I'm so afraid that it will get messed up! Is there anything I can do to protect it? Should I just suck it up, use it, and if it gets dirty deal with it? What about you ladies who have one? All thoughts and comments I'll appreciate!
