Her bag is "LAI" Luxury Accessories International.......Kim's bag is called the "Wow Satchel" To purchase call 212-794-3874. Kim's particular bag may no longer be available because its a few seasons old, but they should have the bag in other colors. HTH
I just got off the phone with LAI. The python is $3200 and you can have it custom-cut as well, depending on what size you want. The bag also comes in ostrich too, which is $3500.
