Wal-Mart is advertising Halloween costumes for plus-size women as "Fat Girl Costumes" on its website.

The retailer's choice of wording, which was first reported by Jezebel, ignited an outcry on social media.

The company has since apologized.

"This never should have been on our site," Wal-Mart spokesman Ravi Jariwala told Business Insider. "It is unacceptable, and we apologize. We are working to remove it as soon as possible and ensure this never happens again."

Here are some of the reactions from Twitter:

Target landed in hot water for a similar incident last year.

The company's website listed a dress in the color "manatee grey" for plus sizes and in "dark heather grey" for standard sizes.

A customer noticed the discrepancy and wrote about it on Twitter. Target later removed the dress from its website.
