We studied on the development of clothing pressure measurement system for wear comfort of foundations(girdle, brassiere, all-in-one). Measurements of clothing pressure were made on subjects wearing girdles, brassieres, all-in-ones of several type(material, size) using by CPMS(clothing pressure measurement system: Tech-Storm. Co). Wearing experiments have been carried out using nine women in the twenties and six women in the forties. The results obtained are as follows: 1. The clothing pressure applied by girdle was higher in the hard type than the soft type by $5-10gf/cm^2$, also recorded a high clothing pressure at points of waist band line and thigh lateral. 2. Clothing pressure of brassiere with wire was high at the point of underbust line and shoulder strap. Pressure for 40s showed higher than 20s by $6-7gf/cm^2$. 3. The pressures of abdominal part applied by both of girdle and all-in-one were much greater than those of girdle or all-in-one. 4. We demonstrated the adaptability and conformity of the CPMS by inquiring into the clothing pressure of various foundations.
