i once bought a pair of marc jacobs peep-toes that i didn't wear for months. i kept them in their box and only took them out to prance around in at home.
also, i think you can buy these see-through plastic thingies to stick to the front part of the louboutin sole, to keep the red from scraping off.
my first 'major' bag was a balenciaga. i still have it, though it's getting a bit beat up. i'm not all that careful with my bags. maybe because handbags last longer anyway, some brands more than others. prada last forever and i'm really rough with my chloé bags and they're still in perfect condition.
