Details
Your Halloween prelude party is here, and the ladies of Blasé wanted to do something a little different than your typical Halloween party. **Welcome to SEVEN DEADLY SINS at The Forbidden Attic.** We want you dressed as whichever of the seven deadly sins you’re feeling, **with no judgment.** Come as Lust, Greed, Envy, Pride, Wrath, Gluttony, or Sloth and step into a world where you can leave your morals at the door. Join us for an all girl Halloween party like Chicago has never seen. Expect drinks, sections available for deposit, DJs, and an opportunity to indulge in your sinful side from the moment you step into our Forbidden Attic. We promise you’ll be in for a treat… and maybe a trick or two. Don’t sleep. Get your tickets fast, and we’ll see you in the attic.
