It's an Grand Revival pattern. The bag is reversible so not as straight forward to make as I expected and I simplified it by excluding the pockets.
The Grand Revival range has a casual feel overall but I decided to make it with fabric that could be used for a casual evening out. It's black silk with a metallic and red brocade. The alternate side is black linen. Here's the result - in hindsight a more structured pattern may have worked better but the gift was gratefully received none the less.
For those of you interested in bags, Amy Butler has a terrific range of bag patterns as well.
