Abstract: The thermal insulation properties of one piece of clothing are different in different wearing methods. The wearing method of clothing was deconstructed into three factors in this paper, including body surface area coverage, clothing openings and sectional fabric wrinkled up. Based on these three factors, a piece of clothing with adjustable wearing methods was developed. The objective tests based on Human Ergonomics principles and the subjective evaluations in wearing trials were conducted. Some key elements were evaluated and optimized in clothing construction design, including the positions of unzipping the placket zipper, the positions of unzipped sleeve attached to the body, and the positions of detaching (rolling up) sleeves on forearms. Finally, the clothing with adjustable wearing methods was developed, which will be used in the following experiments of quantitatively evaluating the effects of the different wearing methods to clothing thermal insulation properties.

Key words: colthing, wearing style, thermal insulation, wearing trial
