Group Protests Revealing Halloween Costumes For Young Girls

Sexy costumes are the bread-and-butter of Halloween revelry, but one group is urging children to hold off on the revealing nurse outfits, at least until they get older.

Concerned moms organized a SPARK (Sexualization Protest: Action, Resistance, Knowledge) summit to remind kids, "there are lots of other ways you can dress on Halloween."

Diane Levin, author of So Sexy So Soon: The New Sexualized Childhood and What Parents Can Do to Protect Their Kids tells the New York Post, "I think we're in big trouble. Halloween costumes for seven- and eight-year-old girls and even younger have become downright titillating, and for tweens and teens, the vast majority of those sold in stores and on the Internet are unabashedly sexually alluring."

Rubie's Executive Vice President Howard Beige says traditional, non-scandalous children's costumes are still popular, but they're being purchased by increasingly younger girls.

"Today, princesses are probably the most popular theme, but the age group is getting narrower -- younger, ages 3 to 6. Our size large is way down [in sales] when it comes to princesses."
