The Birkin Bag:
The Birkin bag came about when Jean Louis Dumas (Chairman and former CEO of Hermes SA) caught the actress Jane Birkin fighting with her straw bag as she was trying to store it in an overhead compartment on a plane. At that point he decided she needed a better bag and he was going to design her one. The idea of the Birkin bag came from the Hermes Haut-Au-Courrois, meaning high belt. The HAC as it is referred to today was used in the late 1800’s to carry riding gear i.e. saddle, riding boots etc. The measurements for the HAC are quite large so Jean Louis Dumas tweaked them to make the bag more versatile as well as easier to carry and modern. The Birkin bag is produced entirely by one person called a craftsman from beginning to end. The average production time for a bag ranges from 18 hours for a 25cm to up 30 hours for a 40cm.

The Birkin bag comes in four different sizes. The size of the Birkin depends on the width of the bag. A 40cm Birkin, simply means that the bag is 40 centimeters wide or 15inches. The standard sizes are 25cm, 30cm, 35cm, and 40cm.
