it is very hard to downsize the contents of your bag. I had to do it, it hurts my back if the purse is to heavy, I use a wristlet instead of a wallet, and less stuff in makeup bag, one gloss, compact, chapstick, eyedrops . another wristlet for diabetes stuff and meds.
Just a smaller calander book , instead of heavy coach agenda. So much lighter now and I dont find that I am missing anything.
