I have a couple of bags I love, but when I try to wear them I end up changing bags that same day and going back to the ones that stay put and then neglecting these nice bags that slip off for a while. They are the ones that are so aggravating and just will not stay put on my shoulder and I have to constantly adjust them. Some have one strap and some have two handles. Do any of you have a solution that works and either does not show or looks nice if it does show to the problem of some of my purses slipping off of the shoulder. I was thinking of using a couple of inches of mole skin taped to the underside of the one strap bags, have not tried it yet, but was wondering if there is anything out there for this problem with some of my bags. Maybe a neoprene or rubber or suede strip with a bit of Velcro that could adjust...or something. Mabye a clear rubberish pad that the straps could slip through? Has anything like that been invented? Does a solution exist? Also, is this a common problem, or just me?
