Abstract
This study provides basic research for developing dress forms of women's wear making. This study compared the average body size of Korean women by investigating the shape, composition and size of 417 dress forms for pattern making, sold at Korean and international online malls. The results showed that Korean brands produced torso-type and torso-crotch-type (94.13%), torso-type was the most dominant type made by Japanese Ki and French St (${\geq}80%$), and all US Al products were whole-body-type. The most common used internal filler of the dress forms was urethane for South Korean companies and paper for Japanese Ki and French St. In most cases, cotton was used for outer materials. Alternatively, linen and rayon were used as outer materials. Al did not indicate the materials used for filler and outer layers. Additionally, the sizing system of dress forms was commonly presented as a Numeric type. In addition to Numeric type, Ki presented body type + usage and Al used character type. When the dress form size for the average bust size of each age group was evaluated, waist measurements were smaller than the corresponding bust measurements. Dress form was presented in the KS interval and was compared with the $mean{\pm}1{\sigma}$ interval of each age group. The majority of the dress forms produced in South Korea were for body shapes in their 20s.
