Main aim is to create a method of virtual reconstruction of historical clothes. We applied 2D CAD, Clo3D, and CG tools to find the relationship between outline shape of skirt, properties and construction of garments and textile materials. We used contemporary fabrics which are similar to historical prototypes by changing physical and mechanical properties. New method includes 3D -to-2D flattening; finding the air gaps in "avatar - skirt" system; choosing textile materials and number of underskirt garments; generating of digital replica. The adequacy of historical prototypes to its virtual replica is full due to CAD, new developed modules, and data base.
