I am considering buying this bag now and I jsut wanted to ask a few question for people who have the bag just to see if its something that I really want... Do you have it?? How long have you had it?? Does it age nicely?? when it does age...is it very "Harsh" ?? (ex. Wrinkling folding sagging??) Do you ever have that moment of regret buying it?? is it hard to upkeep?? THANK YOU!!
