An overskirt is a type of women's short skirt which is draped over another garment, such as a skirt, breeches, or trousers. Although peplum is often used as another term for overskirt, it should not be confused with the peplos or "peplum dress", which was worn in ancient Greece.

A peplos is a body-length garment established as typical attire for women in ancient Greece by c. 500 BC, during the late Archaic and Classical period. It was a long, rectangular cloth with the top edge folded down about halfway, so that what was the top of the rectangle was now draped below the waist, and the bottom of the rectangle was at the ankle. One side of the peplos could be left open, or pinned or sewn together. In Latin and in a Roman context, it could be called a palla.
