Someone at Walmart needs an etiquette class and some lessons in how not to categorize Plus-size women's apparel.

CNN:

Walmart found itself sending apology tweet after apology tweet Monday after the Twitterverse raked it over the coals for a major goof on its website.

For whatever inexplicable reason, the retail giant's site featured a Halloween category, titled "Fat Girl Costumes."

You won't find it there now, thank goodness, but it stayed there for a large part of the morning -- and long enough for multiple screen grabs.

Actually, according to the video, it was up for several days.
