I found a fabulous pair of riding boots with a shaft circumference that will actually fit my tiny calves! However, they're only available in my size in the dark brown.

My neutral staples are black and khaki. I just don't wear brown and have no desire to begin adding it to my wardrobe, except in this one case. I know this color will look great with denim and khaki, but...

Can I treat them as a go-with-everything neutral color?
Can I wear these boots with black skirts and pants?
Can I wear them with sheer and opaque black tights?
Or am I better off waiting for a casual black boot?
