>The rise of the sexy Halloween costume probably began sometime after the 1960s, but its biggest pop culture moment came in the 2004 movie "Mean Girls." Cady, the naive heroine, arrives at a Halloween party dressed as a gory bride of Frankenstein only to find the popular girls dolled up as a sexy bunny, sexy cat and sexy mouse. Oct. 31, she realizes, "is the one day a year when a girl can dress up like a total slut and no other girls can say anything else about it." Sex-advice columnist Dan Savage once called the yearly display of flesh a "Straight Pride Parade." "Halloween is now the big public celebration of straight sexuality, of heterosexual desire," he wrote in 2009.
