I'm looking for someone who has this bag - I'd like to know how the leather wears after time. Does it start to look really faded and worn (as if the metallic is rubbing off) or do you think it has held up really well with a lot of use? I'm comtemplating getting it (before it sells out! I just missed out on the iznik yellow! grrr...), but I'm concerned about how the color of the leather will hold up.
