Target had an ad for a kimono maxi dress. The standard sized version of the dress is available in "dark heather gray" but the same color in the plus-sized version was described as "manatee gray."
Manatees are large marine mammals that are sometimes called sea cows.
An Orange County woman tweeted about the color discrepancy and it got a lot of attention.
Target caught wind and issued an apology. They are also saying they're working to fix it.
