The horror of Halloween shouldn't be found in nip slips and exposed muffin tops.

This year, Nicole Richie has a public plea for ghouls and girls around the world: don't "dress slutty!"

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

Although Richie, who is mom to Harlow, 3, and Sparrow, 2, has donned some provocative outfits in the past, her Halloween costumes in recent years have been rather wholesome. In 2009, she covered up as the White Rabbit from Alice in Wonderland, and in 2010 she dressed conservatively as Margot Tenanbaum from The Royal Tenanbaums and also as Jessie the Cowgirl from the Toy Story films.
