This report provides theoretically a comparative study of basic pattern of waist loose type and fit type. Following experiments on basic patterns were conducted : 1) Experiments on the theoretical derivation of basic pattern making; 2) experiments on the theoretical verification of basic pattern making; 3) experiments on the body measurement as case examples.
The results are summarized as follows :
1) Under convex points of upper trunk, there were differences in the surface angles between waist loose type and fit type, accordingly the element lengths of each parts differed. Therefore the lengths of basic pattern differed.
2) The difference of element lengths was larger in back pattern than in front pattern.
3) It was devised to change from basic pattern of waist fit type to loose type, utilizing “the difference” of element lengths.
4) Even the three-dimentional form of armhole was the same, the sole of pattern armhole differed between in the case of waist loose type and the fit type.
