Calling all Prada PFers who owns the antic gauffre messenger in natural, how do you baby it? I hv mine last month and only use it a couple of times, i found that the leather at the back was worn out due to constant fiction with my hip, also the color of my jean was transferred to it. BTW, i find it on the heavy side and my shoulder feels sore aft a hr of shopping. Any similar experience? Advice? Tia.
