Yea, I know... I bought one about 4 years ago. Almost time for a new one.
You know, to me, a slip is just the thing that keeps my skirt or dress from sticking to my tights. I never thought of one as a "privacy" shield! I've tried using hairspray to solve the problem, but got tired of sticky thighs. I could care less if someone wears a slip; in fact, I am sure most of my colleagues don't know what one is.
If we could invent something that stopped the stickiness problem, we'd be millionaires.
