If you've been working on your Halloween costume since September, this is the party for you. Once again, the Peabody's annual Boo Bash is home to one of the city's fattest cash costume prizes. A thousand smackers goes to the best outfitted. Or rather the best outfitted as determined by judges including ALICE 107.7 DJs Heather, DC and Poolboy; KATV's Pam Smith and Christina Munoz, and chef Donnie Ferneau. Last year, a "Where the Wild Things Are" duo jointly won the prize. Their costumes looked good, but Lady Gaga in a meat dress they weren't. In other words, bring it creative Little Rock. Popular local cover bands CRISIS and Tragikly White provide the soundtrack, which will be augmented by "a spooky light show." Don't want to try to fit the hoop skirt in your Marie Antoinette costume in a cab? The Peabody's offering special rates and one free ticket for guests. Only those 21 and older can attend.
