This is how I define a "but I don't want to get out of bed" outfit. My husband's ironed shirt, jeans and a bun. My only saving graces today were the red heels, lipstick and an animal print belt. You can fool anyone with an animal print belt -- only people who mean business wear animal print. Everyone knows that.
