It's probably easier to define the points of difference between a kilt and a skirt. A skirt can have as many, or as few, pleats as the designer chooses, while a kilt will always have pleats, but only at the back. A kilt wraps around the body, and you secure it with a buckle or pin. A skirt can be of any style, pattern, or length. A kilt will always be a tartan, woven in tartan's particular, distinctive style. While a kilted skirt will have many of these features, it would be wrong to say that a kilted skirt is the same as a kilt because there are fewer rules or conventions around the skirt's design or who makes it.
