Abstract: Based on the 160/84A Standard Female Basic Collar Line, this paper discusses a simple and intuitive design method of lapel collar structure. Through the analysis of the factors affecting the fit of lapel collar, the method of dividing the collar seat is adopted to make the collar fold line more fit the neck. At the same time, the rationality of this method is verified by 3D virtual experiment, and the value range of the inclined angle of collar with different body-fitted degree is obtained, which provides a theoretical basis for the optimum design of collar structure.

Key words: lapel collar; division collar; fold line reduction
