"Vampire Diaries" star Ian Somerhalder had a brilliant idea for his costume this year -- and just had to raid the show's wardrobe department to get it!

About the get-up, Ian tweeted "early morning on set. Paul Wesley is here, It's always strange to hang out with the monster you dressed as for Halloween..."
