I also have it in Havane and I LOVE this handbag. It may be a bit small in stature but it expands because of the pleats and fits everything I need to carry! I also love the chain. It's so comfortable on the shoulder!
It seems to be a precursor to the mask collection with just a small vachetta decoration. I love this handbag!
I have seen several people carrying the Pallas lately. I think it's beautiful, and even more so when the owner chooses an accent color for the top of the bag that has plenty of contrast with the Mono. Something in a red or berry shade would be my choice.
