Abstract
The design of dresses should be conceived with close relation to all elements of physical forms of those who wear the dresses. Continuing from last report which dealt with women's neck, I have investigated in the present paper forms of the trunk of women, and tried to classify the forms into several types and studied the frequency of the appearance of each type. The examinees and the conditions of measuring are the same as Part 3 of this series of studies. Twelve items mainly around the trunk part were measured. Moreover, I took photographs of the front and side figures of 271 girl-students who wore a brassiere and a corset by the silhouette machine and measured the angles of shoulders, breast, back and hip on the photographs.
Classification of forms and rate of their appearance :
1. On the basis of the correlative distribution of differences between biacromial breadth and waist breadth and transverse diameter of hip and waist breadth, I classified forms of the trunk into nine types. The rate of appearance of each of these nine types was investigated.
2. Forms of the trunk were also classified by the correlative distribution of angles of the back and the hip.
3. Special forms observed in twelve parts were examined and their appearing rates were calculated.
