Do you think this bag has enough edge for someone who doesn't want a bag that looks like a work bag? Does it look a bit fun too, or would it be considered pretty conservative? I have not seen one IRL. I read some complaints about the straps not staying up...is that a general problem? I'm wondering if it is always a problem...I have had bags where the strap falls unless there is some weight to the bag and then it's not a problem. I like double strap bags, but not when this is a problem.
