Crinoline

petticoat

The crinoline is a 19th century form of the hoopskirt; a « hooped petticoats » or a framework of light metal without petticoat, the « cage crinoline », that held out skirts without the need for multiple layers of petticoats (which had been the previous method used). Crinolines were widely worn in their original extravagant form from about ca. 1854-1866. Since then, the term has been used for various contrivances to hold out skirts in more directions than a bustle; however, these latter-day crinolines do not rival the Victorian original.
