The paper describes the general understandings of the concept of comfort and its various components described in the literature. There is given an insight into garment fit problems and existing evaluation methods. The study aims to explain the importance of the anthropometry and the impact of its change and development on the improvement of garment fit provision. The possibilities and benefits of using 3D body scanning technologies in anthropometric studies are observed to explain options to improve the garment sizing and fit evaluation processes. The possibilities provided by modern computer-aided 3D design systems for development and analyzing clothing products are considered. The study includes examples of 3D scanning and virtual prototyping capabilities for assessing the fit and appearance of clothing, highlighting the shortcomings that hamper research into the interaction between the human body and clothing.
