I always read about Garden Party talk, but I really am out of the loop. Can you all chime in and give me some lessons. Nathans new Garden Party was a real beauty and I would love to know more about the bag. What options can you get for the exterior? Are there limited leather choices? Are there better choices than others for this type of bag? (what is recommended) What about the interior of the bag? Again, options? Sizes of GP? (I am aware of the codes for sizes, but have no clue) Costs of sizes? Are GP hard to come by? Anything you can share would be lovely.
