10 Hilarious Halloween Costumes Based on Jennifer Lopez's Lyrics

What you need: Get yourself a "Goodnight Moon" t-shirt, then show up to a Halloween party like you're in on a very big secret (because you are).

What to say when someone asks what you are: Embrace the role you were meant to play — the one where you're kind of just at the party because you have to be; if it were up to you you'd be watching Netflix — and say: "I have spent all of my life, waiting for tonight."
