The PM is a good sized shoulder bag. The GM is Reaaaally big! I think there is one on L-Z.
As a side tip, I called New york to find out how much it costs here in the US. If you take the selling price plus tax and compare it to the selling price in Paris minus Tax refund, the difference is somewhere between $700 to $800. That is almost a round trip ticket to Paris! So, it pays to go to "The" store.
