Thanks, everyone. The Boden conker (rust) cardigan sweater is on its way. I ordered it by mistake. Long story. Still agonizing about the other one.
Robin, that is a good way of describing the effect of earth tones on black. Soothing. I like that.
Kathie, I am always surprised by how well black works in my wardrobe. Not sure why but it does.
Janet, that is another good way to describe black. A foil for earth tones.
