Yup, you're right. That's why I never have much luck buying a bag online that I have not tired on IRL.My advice...just go check some bags out in the store. So many times I see a bag and I love the look of it, but it just doesn't work for me for whatever reason. I just bought an Ergo Tote last week and at first I wasn't sure I liked it, but after carrying it for a few days I fell in love. So you just never know, sometimes you have to try them on to see what you like the most. Let us know what you decide on, and good luck with your surgery.
Thanks for all the great advice, everyone! (I may try to sneak to the mall after work today if I have time!)
