Abstract
Paper presents research on dynamical behaviour and fit analysis of customised diving suits. Diving suits models are developed using the 3D flattening method, which enables the construction of a garment model directly on the 3D computer body model and separation of discrete 3D surfaces as well as transformation into 2D cutting parts. 3D body scanning of male and female test subjects was performed with the purpose of body measurements analysis in static and dynamic postures and processed body models were used for construction and simulation of diving suits prototypes. All necessary parameters, for 3D simulation were applied on obtained cutting parts, as well as parameters values for mechanical properties of neoprene material. Developed computer diving suits prototypes were used for stretch analysis on areas relevant for body dimensional changes according to dynamic anthropometrics. Garment pressures against the body in static and dynamic conditions was also analysed. Garments patterns for which the computer prototype verification was conducted were used for real prototype production. Real prototypes were also used for stretch and pressure analysis in static and dynamic conditions. Based on the obtained results, correlation analysis between body changes in dynamic positions and dynamic stress, determined on computer and real prototypes, was performed.

Summary
Diving suit is garment type for special purposes, for which is necessary to satisfy high criteria of comfort, fit and functionality. Considering high demands for fit in specific dynamic conditions, we investigated application of computer 3D pattern construction directly on surface of a 3D body model and flattening method for separation and transformation of discrete 3D surfaces into 2D cutting parts [4,5]. In order to verify the proposed method and complete development process and prototype in real conditions of use, we selected female test subject, which is successful and multiple awarded free diver [10] and a male test subject, which is active spear fisher and a successful diving suits manufacturer [11]
