I'm beginning to think I'm the only Vuitton owner who likes naturally darkened Vachetta on my mono canvas bags. I don't take any special care of Vachetta--I like the way it ages into a honeyed brown. I love seeing dark handles on a mono Speedy; it's a sign that the bag is used and loved and not a museum piece. Mind, I've no intention of ever reselling mine, either, so that may be a consideration--but the one used Vuitton I've bought had beautiful patina on the leather, which is why I chose that specific one. Am I totally alone, here? I'd love to hear from some of the more, er, experienced Vuitton fans especially (I'm in my mid-forties)!
