Does anyone know who designs this bag?

HI! This was my auction - I had the Billie for sale and changed my mind. The color of the leather is very original - a mix of rich purple and deep blue. The suede sides are cool along w/the brass cameo pulls. I didn't realize Greendrv had it on her site!
 
I decided I'm too short for this purse after all so back up it goes...it's definitely Mayle Billie that Kiki is carrying - she has one in gray, maroon and black. She also has the smaller style in white.
