I am having problems with my back, so need to use a backpack style handbag. It needs to be reasonably smart for work. I have a lovely Fiorelli one a bit like this: https://fiorelli.com/collections/black-backpacks/products/ally-backpack-black
The problem is that it leaves black marks all over the back of my clothes. Can anyone suggest something similar which doesn’t ruin their tops? Thanks!
