I am hot and cold about black but always have some in my wardrobe. For a long time I used gray, especially charcoal, as my replacement for black. It just didn't seem as harsh. Lately I have been wearing more black again. Now that my hair is gray I wonder if I should switch back to gray?
If I were you, I would wait and see if I miss any of these items - but then I am not nearly as much a planner as you are.
