Not just because the song is instantly catchy or because the Brit singer is dressed up like a vampire (how does she sing with fangs?!?), but because it features a Monster Mash-style choreographed dance.
Bonus points for giving us some last-minute costume inspiration. If you don’t want to dress up as a vamp, get super meta and dress up as Kate Nash as a vamp. (If you’re still stuck. we’ve put all of our costume inspirations and DIYs in one place to make it extra easy for you to dress up this Halloween.) –REBECCA WILLA DAVIS
