Abstract: This article aims to explore morphological characteristics in the neck of the long seat job incumbency male and provide reference for the collar design of the young men's clothing. Extract the human neck relevant data by three-dimensional human body measuring and analyze the data from the section of the neck shape, neck circumference form, neck height shape, neck curvature shape, neck solid form respectively. The study shows: Transverse-longitudinal ratio of cervical root and transverse-longitudinal ratio of middle neck spread over a definite value, neck circumference of man increased as age; there is a strong linear relationship between neck middle circumference and neck root circumference. Divide the necks into three categories according to the cervical curvature change; There is a strong linear relationship between front neck length and rear neck length；Divide men's neck into four dimensional morphology and compare the measurement results with neck type of general young male, then provide data reference for men's fashion collar design through the analysis of three-dimensional shape of the neck.

Key words: on-the-job male, collar style design, neck morphology, three-dimensional anthropometry
