I don't think so. Mine almost a year old and I've carried it pretty consistently in that time; plus it's kept pretty full, too. Still stands up by itself, too.
Yes mine stands too..just feel the canvas is much softer after weeks of use. I saw someone elses that looks out of shape when worn crossbody. Could be the weight of the bag on the 2 little d-rings. Not looking forward to mine being like that
