Can anybody ID this white bag from The Sartorialist?

I'm going to take a wild guess and say Marc Jacobs....but it could be Marc by Marc Jacobs....the zipper pulls make me think this way but I could be wrong....any other guesses??
 
That's a tough one! It looks like it's a convertible bag because of the rings on the side. If it had a gold, chain strap, it would definitely be Marc Jacobs. Otherwise, I'm stumped!
