Slutty Halloween costume?

My boyfriend made a comment that I should suprise him in bed as a slutty cop and I had actually already been thinking of somthing slutty for him.

Bunny, cop or a slutty candy corn dress.I bought long above the knee socks with black rufles at the top that are pretty slutty and I love them!!! A black pair, a black and white pair and a black and orange pair.

What costume do you think and with what socks???? What is most slutty??.
