Anyone who thinks Halloween costumes are just for kids has clearly never been to the Monster’s Ball Costume Party. The bash invites grown-ups to get into the holiday spirit by putting on their spookiest, silliest, or timeliest costumes and heading to the Clarion Hotel for an evening of festivities.

The party kicks off at 8 p.m. when the doors open and the cocktails start flowing. The open bar offers up all-inclusive libations for the first two hours of the evening, and then you can pay as you go. The best costume scores a cash prize, so dress to impress if you want to fund a full evening of cocktails. The DJ will spin hip hop, R&B, and top 40 hits until 2 a.m. Tickets start at $35 for individuals and $60 for a table.
