OK, here's the deal... i went out yesterday in my new GAP dark indigo jeans, which despite washing twice before i wore them had managed to rub off colour onto my cream toile herbag by the time i had got home. luckily i remember someone very usefully suggesting a nailbrush and baby shampoo to remove it, and luckily it came out. however i'm now getting paranoid about denim rub-off when i get my new vermillion swift birkin, as this would be a disaster and not fixable by baby shampoo and a quick wash. do you watch what colours/denim you wear with your expensive H bags in case this happens?? or am i just destined to wear pale blue denim when i have my precious birkin on me???
