So, I have noticed that when I carry my soho disco bag one side flops in on the top. Only the back side does it, never the front. I don't carry a ton in it and maybe if I did, it would fill the bag more and it wouldn't sag in but it bugs me. I've only carried it a handful of times. Wondering if this is just the nature of the bag's design or if it's a flaw. When I have to lift or move the bag in any way, it just caves in on itself. Thanks.
