Fashion experts when designing new clothing firstly focus their attention on design, style, colours and fit of the product, and then they have to consider structure and materials of the developed garment. However, all these components of the garment design, namely the fabric structure, composition and finishing will influence the sensorial and thermal comfort of clothing. In the paper, selected parameters of clothing comfort, namely fabric drape, friction coefficient and thermal & evaporation resistance as well as special methods of their testing are shortly described, and the possible effect of these paramaters on clothing design is outlined.
