Abstract: The silhouette of the chest is critical to the appearance of the women’s dress. The structure processing technology and parameter design will directly influence dress coinciding with the figure and global balance. To take the 165/84A figure model as research object and eliminate the fabric’s influence on the structure, the body blouse is made by increasing the chest height by 1 , 2 and 3 cm respectively. To get the pattern of the structure with draping, the variation of displacement of different process points of the body blouse pattern in different chest heights is observed and the change rule is summarized by the analysis method of plane pictures stacking. The result shows that the chest measurement increment and the dispersion of the upper and lower chest measurement will increase by equidifferent with chest height increasing by 1cm, the variable is all provided by the front bodice, the breast convex amount, shoulder dart and waist dart will increase correspondingly, and the measurement size of the back bodice don’t change. The pattern of body blouse in this study will serve as a foundation for structure design in making other body blouses.
