The white bag is the Marc Jacobs Perforated Leather Brigitte, and eLuxury (I know, I know) has it available (and you might try Bergdorf or Neiman, too). I have a post up inquiring about the other bag...I have no idea what this one is, but if you find out please let me know! I am dying for more info!
That was me who posted on the brown bag previously. The photo in US magazine shows a closer shot of the bag and handle appears to be a brass-type chain rather than rope. Still no clue as to whose bag this is, though.
