paris seems to be carrying it alot this year- i think its a lovely classic and classy piece!
anya hindmarch would be my guess. the hardware has the signature ribbon shape.
I believe it's by Anya Hindmarch. She always has those little bow-shaped hardware. I don't know the name of the bag though. Sorry.
It doesn't look like anything in the current AH collection. None of the details are even close.
