Females wear an underskirt or petticoat with an outer skirt and accessories such as collars. The underskirt, or petticoat layer, is called "sokchima". This fashion required an underskirt, which was heavily trimmed with pleats, flounces, rouching, and frills. Some wear longer-length prairie skirts with a slip or underskirt to preserve their modesty. It fully covers the underskirt ("poale") except for, in some areas, the hem. Many incorrectly show the underskirt in blue and not argent.
