Could you be the big winner at the Clarendon Ballroom’s annual costume contest? (HiBall Events)

Check out our list of the top offbeat Halloween events -- including a doggie costume contest and a heavy metal-themed cocktail event -- or browse our longer list of all Halloween parties and costume contests for adults.

Two last pieces of advice: If you’re heading to any of the big Halloween events downtown this weekend, such as the Nightmare on M Street, you need to read our blog post about how Metro track work could derail your fun. And if you *still* haven’t finished your costume, we’ll have experts from the Backstage costume shop offering advice in tomorrow’s Got Plans? chat. Maybe you’ll win $3,000 in the costume contest at Elliot in the Morning’s Halloween Bash on Friday night.
