The dust bag that comes with this fakey fake has Marc Jacobs written in two different colors, Marc is dark and Jacobs is light. I bought my Adina on eBay and it came with the same kind of dust bag, and it's been bugging me ever since. I'm sure the bag is authentic, but why did it come with a weird dust bag? Is this the Marc by MJ dustbag? My only conclusion has been that since she bought it at Saks, presumably on sale, she just got an errant Marc by MJ dustbag instead of the "right" one. Can anyone clue me in on this particular styling of dustbag?
