I am thinking this question has plagued us Chanel lovers but I was just wondering if I need to stop. I have a Black Boy Ruthenium, So Black Chevron, Black O-case Gold, Black Classic Ruthenium (that I just bought last week) and last night I pre-ordered the So Black Mini with Crumpled Calf. I do have a Rainbow Boy when I feel like it, but should I stop buying black Chanels? Or are they different enough?
