Abstract: In this paper, the related factors influencing the sleeve of the new prototype are analyzed by making samples and constructing theoretical models. According to the research, the factors of sleeve matching vary with the body size. When the shoulder slant is adjusted, the effect on the sleeve fitting factor is not significant, and the main influencing factor is the angle of the sleeve. In the structural design of sleeve fitting, the angle between the angle and the inclination angle of sleeve fitting was nearly linear. The corresponding factors of sleeve fitting in different styles were quite different.
