i've had my Denim Neo-Speedy since Thanksgiving 2005, which was quite soon after it was released, and i haven't really noticed anything except the patina
i read about the color fading with the pink denim that's why it made me worry a bit. and now im thinking i wouldn't want a faded bag, that would def look so 80's hehe
My friend has blue denim mini pleaty for almost a year and the only difference on hers is the patina. I have one but only since December. I love my mini pleaty!
I'm only guessing but I would have thought that it would only fade if you washed it and that would just be the craziest thing to do so I don't think they will fade
