I recently got a Tivoli GM and am worried that when I use it as a shoulder bag, my clothes might rub off on the vachetta strip (that runs along the top of the bag) or on the handles. Should I be concerned? All my LV's have been strictly handheld and this is my first shoulder bag. I've read in other posts that this happens sometimes with jeans, but I was just wondering if any of you have had any bad experiences with rub off on vachetta with just regular clothes. TIA.
