Okay, I can't seem to get off the cardigan obsession! It is the first upgrade wish I've identified for Fall...sorry for so many cardigan posts!

I found a medium grey cardigan that is really beautiful...soft, great style, cashmere blend, price ($125) is fine, but high enough that I need to be sure it will be useful.

The issue is that my neutral is black. I do want to find grey trousers, but at this time all mine are black. So...to me, black trouser, any color top, and black cardigan makes an outfit. Jewelry or scarf and done.

Would black trouser, any color top, and grey cardigan look disjointed? Would I need to be fussing that the top had both black and grey...or that the scarf did? I'm having a hard time feeling like the grey would be as easy for me to work with as the black.

What do the experts think?
