Yesterday I saw a sleeveless denim dress worn open, belted, and layered over a black long-sleeved T-shirt and black skirt. You can see it here.) I was going to try that today but realized my denim dress had long sleeves.
I decided on this - belted with black patent leather belt and worn with black footless skinnies, and black stockings and shoes. (I may go back upstairs and add a black T-shirt, but for now, I'm comfortable and enjoying my first cup of coffee.)
