A self-described plus-size shopper from California posted identical Target products on Twitter - the only difference being the size.
The standard style is described as "dark heather gray." But the plus-size product is "manatee gray."
Manatees are big creatures, often called elephants of the ocean.
The shopper complained that "manatee" was a hurtful reference to her body shape.
A Target spokeswoman says the labeling of the Massimo-brand Kimono Maxi Dress was "an unintentional oversight" and Target will be "fixing the discrepancy."
