Nicole Richie Tells Girls Not To Dress Slutty On Halloween

Anyone who has watched "Mean Girls" knows that Halloween is officially "the one night a year when a girl can dress up like a total slut and no other girls can say anything about it."

Somehow Halloween has transformed from being about wearing scary costumes to figuring out how to make inanimate objects sexy (sexy Scrabble costume, I'm looking at you), and Nicole Richie has had enough of it.

The 30-year-old actress wrote on her Facebook page, "Girls, can we all pledge that we will not dress slutty for this Halloween? The jig is up."

Motherhood must be having an effect on Richie who has worn some pretty sexy costumes in years past. But as Us Weekly reports she has spent the last few years going for more wholesome costumes, like the White Rabbit from "Alice in Wonderland," Jessie the Cowgirl from "Toy Story" and Margot Tenanbaum from "The Royal Tenanbaums."

Richie may have a point for anyone who wants to actually stay warm this Halloween.
