Since I'm fairly new with Louis Vuitton, what does it mean when people say that LV is weatherproof? It's not waterproof, is it? I have been caught in the rain a couple of times and am hoping that I can use ScotchGuard or something on my mini monogram Lucille, or is that on there already? I read something that the Damier is more weatherproof than the monogram? What does everyone carry when it's rainy outside?
