This study was to select the measurement points of the girdle and the all-in-one. 15 subjects (age 30-40) were chosen by % body fat to represent various physical types. Subjects tried on each garment; a girdle and a all-in-one, in turns. Measurement points in the underwear were selected according to the parts of the human body. The characteristics and the surface area of the each garment were considered carefully when the measurement points were selected. Selected measurement points on the girdle and the all-in-one were chosen from the anterior midsagittal line, the side-seam line, and the posterior midsagittal line.
