              A material can have different modules of compression ability along the warp and
           weft. Knowing both modules, it’s possible to cut the pressure garments in different
           directions in accordance with desirable effects, garment structure, human body
           morphology, etc.



           13.5   Sizing system for pressure garment

           13.5.1 Garment labeling
           Different styles of garments and different manufacturers have a variety of sets of size/
           type systems for the human morphology of the populations of different countries and
           regions. Besides, the different regions have different categories and types of pressure
           garment distributions, but the general methods of pattern block drafting and labeling
           are similar (Qiming and Wenbin, 2003; Koszewska, 2004; Hong et al., 2006; Zhe and
           Kuzmichev, 2017, 2019). These systems were designed to meet the physical charac-
           teristics of most people with lower production costs, by reducing the number of gar-
           ment sizes to satisfy the body characteristics of most people. As usual, these systems
           are good for the garments produced by pattern blocks with positive ease allowances,
           when the sizes of ready-to-wear clothes are bigger than the body measurements in
           total cases.
              There are various size charts for women’s and men’s top and pants (underwear),
           girdles, socks, etc. using different sizing systems for each category. In the market,
           the labeling of pressure garments is the same for common garments, but the real sizes
           are smaller for the needs of fit and compression.
              For the top of pressure garments, which cover the torso, the size charts usually
           are based on the letters “S, M…” or values “46, 48…” (Europe), “36, 38…” (US),
