I never liked bags that fit under my armpit, but I love the Sophia and suffered with it. But it got to the point that I can no longer wear a bag like that, my arm goes numb from being cocked out like a chicken wing when a bag is jammed under my armpit.
So, I got rid of most of my large collection of Sophia bags, but I've kept 3 and have found ways to make 2 of them work for me.
For my black embellished Sophia I just bought another strap and a pair of silver spring clip O rings to make it hang right. The strap didn't hang right just attaching it to the D ring that was already on the Sophia, but the addition of another pair of O rings did the trick.
For the black woven Sophia with the gunmetal hardware, I bought 2 sets of gunmetal spring clip O rings and they add enough length that I can comfortably carry it again.
Sorry for the terrible photos, this house has bad lighting for taking photos.
