The label for the same dress in smaller sizes described it as "dark heather gray."
Target apologized for the label.
Spokeswoman Jessica Deede called the labeling of the Massimo-brand "Women's Plus-Size Kimono Maxi Dress" ''an unintentional oversight."
She said although manatee gray was a seasonal color, Target was "fixing the discrepancy." She said the item was removed from the company website.
