I think the retro defines the CB line but it is hard to get into when you're holding it. The papillon is adorable but I don't like how my stuff rolls around and moves around when I carry it. I have both and I find that the retro is more controversial... either people love it or they hate it..I even got one comment that it looks like a "grandma wanna be cute" bag! As for the papillon, EVERYONE thinks it's cute.
