Skirts and dresses of thin or clingy fabrics are worn with slips to make the material of the skirt drape better and for modesty. Skirts started fairly narrow and increased dramatically to the hoopskirt and crinoline-supported styles of the 1860s; then fullness was draped and drawn to the back by means of bustles. Skirts or dresses are the garments of choice for many women in formal situations, such as weddings. Skirts and dresses are, like other outer clothing, usually worn with underwear.
