Dress, Cardigan, Top, & Skirt: The Underground Pearl

One of my favorite colors of all time besides black and white, is Emerald.
I can't get enough of it.
Maybe it is/was my love for The Wizard of Oz and the Emerald City?
Ha. I don't know.
When Fall rolls around I remember how obsessed I am with it.
What color do you love in the Fall and Winter?
