A costume distributor said Wednesday that it had stopped shipping its “Kung Fool” outfit to retailers after Asian-American groups complained it was racist.

Groups including the Organization of Chinese Americans, the National Asian Pacific American Legal Consortium and the National Asian American Student Conference said the Halloween costume perpetuates stereotypes. They also called for Disguise Inc. to remove it from retail stores.

The manufacturer, headquartered in Poway, Calif., said the adult costume which includes a mask with buckteeth and slanted-eyes has already been shipped to retailers across the country, including Party City and Wal-Mart. No more will be distributed.

The outfits now belongs to the stores, Disguise said, though the company will accept returns from retailers.

In a letter to Disguise, the Organization of Chinese Americans said the costume singles out and ridicules Asians.

“We’re perpetuating this racial ignorance instead of really celebrating the diversity of this country and portraying people more realistically in these costumes,” said Christine Chen, OCA executive director.

The group noted the costume includes a headband with the Chinese character for “loser” on the front of it.

The company said the costume is “a comedic parody of a Kung Fu karate character.” Spokesman Chris Wahl said Disguise has stopped selling the costume on its Web site and was accepting returns from retailers before Oct. 30.

“Disguise apologizes to any group or individual who may be offended by this costume and mask,” the company said in a statement. “No insult or offense was intended against any race, ethnicity or individual by the sale of this product.”
