If you're trying to win over customers this Halloween, this is certainly not the way to go about it.

Walmart apologized on Monday after sparking outrage for labeling plus-sized Halloween costumes as "fat girl costumes" on its website.

"This never should have been on our site," a spokesperson from Walmart told Mashable. "It is unacceptable, and we apologize. We are working to remove it as soon as possible and ensure this never happens again."

The issue was first reported by Jezebel on Monday, who called the company's costume section "truly the hottest of messes."

People expressed outrage the most public way they knew how: on Twitter.

"Fat Girl Costumes"? Really, @Walmart? Who thought that would be an appropriate title for a public sales page? Come on. — kristen garris (@kristengarris) October 27, 2014

The company removed the all plus-sized items from the category at around 10:30 a.m. ET, leaving the "Fat Girl Costumes" page empty — though the category remained on Walmart's website.

Walmart has since redirected that category page to one titled "Women's Plus Size Halloween Costumes," which appears to be a mix of plus-sized costumes and non-plus-sized costumes.

The Walmart spokesperson said the company is investigating the matter.
