My guccissima hobo has worn off on the corners. I purchased the bag about three years ago and I have only worn it about 5 times. It has been in the dust bag sitting in my closet all this time. I was frustrated to see my corners discolored when I retrieved it from the closet. I returned a gucci bag years ago because of this problem. You would think that Gucci would have improved this situation. Any suggestions on what I can do???
