Honestly I feel that the Reverse canvas clashes with the Damier Ebene.
Have you considered these? The Lively Chain is very playful, red and coral notes on one side, and blue notes on the back.
But the most beautiful is the classic Fleur the Monogram I believe.
I think they are both gorgeous but I would choose A from a practical view as it is held in place more as it is attached to both handles. The other one could move more over the bag with it being long and that would probably annoy me.
