Inenarrable

Inenarrable means :  which can't be told.

This bag can't be described, it's a pure poetic item... 

You can wear it in it in different ways. With its detachable pouch and its tiny wrist-strap, it turns into a clutch for the evening, while during the day, with its huge shoulder strap, it becomes all or part of your look, almost a piece of clothing.
