I don't find them similar at all. The Baby Cabas is a wider bag (more east/west), while the MC tote looks longer (north/south). I love them both! I already have the baby cabas and love it, but now I'm liking that MC tote! IMO these are 2 totally different bags, the only thing I can see that's similar is the black leather and chain and leather handles. I would keep both if it's possible.
