Sizing and fit for swimsuits and diving suits 277

In terms of process optimization and applicability of the method in real
manufacturing condition, additional criteria, such as the number of required additional
interactive corrections on 2D patterns, position and correctness of pattern connection
segments, and symmetry of pattern parts, can be evaluated, showing better optimiza-
tion and applicability for the flattening method on a custom parametric body model.

10.6 Fit analysis and testing of diving suits

10.6.1 Virtual prototype testing

Beside visualization of computer prototype and analysis of pattern dimensions, inno-
vative CAD systems for clothing construction enable additional assessments of pat-
tern deformability, like testing the garment stretch on the body, in longitudinal and
transversal direction or testing the pressure of garment against the body, depending
on applied physical and mechanical properties. Diving suits have a characteristic
of compressibility, which is caused by specific elastic properties of neoprene material.
In that sense, computer prototypes can be further tested in terms of material stretching
in transverse direction on different body areas in static upstanding position. In order to
assume appropriate fit in wearing conditions, determined values should not increase
the limits of values obtained by evaluation of real materials, Fig. 10.22.
Pressure analysis considers normal collision pressure of garment against the body,
Fig. 10.23. It is necessary to predefine pressure points on which the suit model will
be tested. Points for pressure analysis are defined based on the characteristics and
demands of the suit being tested. According to professional consultations with expe-
rienced spearfisher and professional awarded free diver, specific points are selected for
