This weekend saw Hollywood host two of its biggest Halloween soirees – on the same night. Hugh Hefner hosted one at the Playboy Mansion (which saw Paris Hilton and Hugh's wife Crystal both dressed as VMA Miley Cyrus. #Awkward) while all the A-list seemed to be at the Casamigos Tequilla partay (hello, Leonardo DiCaprio) or The Byrne Notice and Emerson's New York shindig. Anyway, don't worry about sifting through the hundreds of pics, we've earmarked the best costumes of the weekend –and there's still time until Thursday to think up yours: just check out Hot Halloween girls and 2013's newest Halloween characters for inspiration.
