To grasp the characteristics of a gathered skirt when it was worn, the outline of skirts was drawn using a silhouette drawing machine which uses infrared rays and measured the distance from the center to the outline of the skirts. Measured skirts were made of 100% cotton broad cloth and 100% polyester filament Fujiginu. From each of these two materials, three gathered skirts and one tight skirt were made. We measured outlines of each skirt at six different heights.
The shapes of the six outlines were different from, but related to, eath other. The overall average of the distance from the center to the outline of a skirt was larger with a gathered skirt than with a tight skirt. The distortion of a contour obtained through the moving average method from a circle was smaller with a gathered skirt than with a tight skirt. The wave-like unevenness of skirts was more significant with skirts which had more gathers. Correlation between any two wave-like curves was lower for the upper part of hip and higher for the other part.
