         with finished garments, for example, to determine potential excess volume in the
         crotch area that occurs as a result of lowering the waistband or belt level. According
         to measurements taken in the research—crotch lengths of finished products, undressed
         and dressed scanned bodies—it is concluded that trousers are designed for wearing the
         waistband at traditional anthropometric waist level, but already dressed body mea-
         surements show that all the excess volume of the garment is placed in the crotch area
         when the wearer chooses to lower waistband level.
            The potential of the noncontact method lies in the arrangement of size systems for
         large target groups, when the obtained information is centrally processed and used
         further for supply implementation preventing disparities in sizing systems, which
         can occur if the necessary sizes are indicated by each wearer. For clarity, labeling
         of clothes in accordance with EN 13402-3:2014 (2014) [Size Designation of Clothes.
         Part 3: Body measurements and intervals] interval pictograms supplemented by letter
         designations may be used.



         11.4    Design of protective clothing

         Construction of garment is a material composition of the garment, which is charac-
         terized by the number of cut and other details, by materials, by the package of textile
         materials, by the configurations, sizes and connections.



         11.4.1 Ease allowances

         The ease allowance is an algebraic difference of numerical values or (less frequently)
         its relative expression as a percentage of the control measurement characterizing the
         outer surface of the finished garment and its decisive standard figure measurement or
         the corresponding customer’s figure measurement. Depending on the location there
         are chest/bust circumference, waist circumference, hip circumference, upper arm cir-
         cumference, armhole depth, etc. ease allowances, which numeric values for example
         in the case of tights, corsets and extensible garments tend to be negative. Functionally
         distinguishable physiologically minimal, movement comfort, silhouette, etc. ease
         allowances [ISO/TR 10652].

         Научно-ИсследовательскийИнститут ШвейнойПромышленности)onspecial
         clothing structures (male and female) has revealed that the ease allowance of bust is
         required within the limits of 9–17cm. This allowance 5–8 times exceeds the size interval
         for half-bust girth (which is 2cm). This has allowed to increase the interval of interme-
         diate sizes and, accordingly, reducing the number of sizes without reducing consumer
