+1 vote for the edge! It's a beautiful bag and very practical - can be worn as a briefcase style bag or worn on the shoulder, the material is very durable too don't need to baby it. Absolutely love it.
Do you have a problem with it sliding off your shoulders? I went instore and it was sliding off when I wore it as a shoulder bag, not sure if it's because of the lack of weight and if the issue would be resolved once I put my things in it.
