Would you buy a jumbo fabric reissue bag?

Make sure there are no rub spots, which would most likely appear on the back of the purse and corners. Fabric purses can't be repaired. That said if you find one in pristine condition, I wouldn't recommend using it as a daily "driver" for that reason alone.
 
Agreed with jmen up there. Fabric bags really are not "everyday" bags but they are pretty to look at and should only be used on special occasions.
