Still trying to understand Chloe bags... So, are there three sizes, the small, medium and large (for the regular paddy satchel)? Would you say the medium is the most popular? Are the dimensions of the medium roughly 13.5" x 5" x 7"? Lastly, for those with dual citizenship (Balenciaga & Chloe!), which Bal bag would you say the medium Paddy satchel is closest in size? Thanks again!
