I have two porte-monnaie plats and they fit 15 credit cards and papers and lots of cash, or about 5 CCs, folded bills and cash. IMO it's more spacious than the ludlow which seems a lot tighter. I the PMP, it's so useful yet fits into pochettes too! I say get a PMP
Wow, thanks to everyone who replied! I am leaning toward the Ludlow, but who knows what I will actually end up with after I go to the boutique I'll be sure to post pictures as well.
