I am interested in this bag: Coach - New COACH SOHO SIGNATURE STITCHED FLAP Love, love, love it!! I was just wondering if the khaki signature shows dirt? My signature flap is black and does not and I have khaki signature shoes and they don't really, but I didn't know if they put a special treatment or anything on the shoes that they might not put on the bags. And will the handle turn? I thought I'd heard somewhere that the handles darken slightly after use. Thanks!
