The goal of the study presented in this article is to explore the new way to design and produce virtual prototypes of garments, adapted for people with scoliosis. People with scoliosis are faced with everyday problem related to purchase and use of suitable, well-fitted and comfortable garments. Our assumption was that we can improve the appearance and fit of the garment to the person with scoliosis by constructing the adapted garment pattern design, taking into account the deformed areas of the body. For this reason we have applied advanced virtual tools and methods, such as CASP (Curvature, Acceleration, Symmetry, Proportionality), for constructing the garment pattern designs adapted to the 3D body model deformed as a consequence of scoliosis. In this way, it is possible to improve the optical appearance of the garment and its fit to the body. With adapted dress pattern design, we succeeded to design a dress with better appearance of the seams on the back as well as the fit in the area of shoulder blades. The results of the study confirmed that reconstruction process of the basic dress pattern design improves the appearance and fit of the dress to a deformed body.
