Halloween is the one night of the year that women can basically crank the slutty up to eleven and get away with it.  Perhaps it is coincidence, or maybe even divine intervention, but Victoria's Secret recently launched a new line of costumes/lingerie they're calling "Sexy Little Fantasies".  Mr. Blue over at What The Christ? breaks it down perfectly, so here's a direct quote:  
"They basically took the most whorish Halloween costumes they could find and turned out their own high quality versions complete with silk and ruffles and all of the other things that look good on curvy women.  I, for one, am excited to see how many girls actually wear these for Halloween."
I don't think Victoria's Secret intends these solely as Halloween costumes, given the presence of a "Santa" and "Valentine" model and the suspiciously absent "Devil" that would certainly be a crowd pleaser.  I expect the "Air Hostess", "Cowgirl", and "Sailor" to be particularly popular this Halloween.
 

Oddly enough, on the Victoria's Secret Page the name of each outfit starts with "Sexy Little Things" instead of "Sexy Little Fantasies".  Ironic that it reduces to the acronym S.L.T.  Would you like to buy a vowel?
