Overskirt
SHORT RUFFLE OR FLOUNCE AT THE HIP, USUALLY PART OF A BODICE OR JACKET
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.
