Today, the Wantickets office was filled with the Halloween spirit! A headless David Guetta was seen roaming the halls, while a sad Dada Life fan could be heard weeping in her office because she didn’t win tickets to see her favorite Swedish duo. Deadmau5 and Swedish House Mafia even made a surprise appearance! Everyone in the office brought their A game to win the costume contest, serious costumers even donned two looks to up their chances! Be sure to check out the photos of Wantickets’ best office Halloween costumes below! Happy Halloween!
