Chappy, the monogamist's answer to gay dating apps, knows what you're trying to get up to on Halloween. But no matter how hot that shirtless Pennywise bro is, nothing is scarier than having unprotected sex.

In honor of their new campaign, #DressThatD, the app has teamed up with 15 local artists to promote safe sex. The theme of all the works? Condoms, of course.

Pieces by the likes of Amit Greenberg, Sean O'Conner and Cute Brute will be up for auction this Thursday at NeueHouse in NYC, amid a pre-Halloween bash benefiting Housing Works. The digital campaign also features art by Baron Von Fancy, Jessica Walsh, and Paul Octavious.
