I had galliera pm and you are right -it is very small and now have the galliera gm-it is big but not that slouchy and I just got the Mahina XL and it is one amazing,slouchy,sexy bag and the only one I want to carry!
LVLux do you by any chance have a pic of those bags together? Would love to see the sizes in comparison! I feel more and more drawn towards a Mahina, but the prize means months of saving.. Hmmpffh!
