Quality children's clothing should give reliable protection to a child from harmful effects of environment. It should also be comfortable, durable and safe, provide psychological comfort and contribute to natural physical, mental and artistic development, though production and distribution should be economic.

Experience shows that current technologies and ways of production at industrial garment manufactories that correspond to highest standards and use CAD systems [1, 2] cannot always satisfy every customer's demands. Clothing made on an industrial scale often lacks in quality and unique style. Therefore make-to-order companies have such an importance in children's clothing production.

Since the quality of garment depends from design point on how it corresponds with a child's body (it's shape and size) the development of a method of virtual parametric children's clothing design with the help of 3-dimensional parametric child dress form should in many ways accelerate the task of designing new individual garments for children. The development of a 3-dimensional dress form requires methodology for its construction based on biosocial information on child body.

The characteristic feature of a child's body is its constant irregular physiological as well as psychological variability. That is why children's clothing design still remains a byway of consumer goods manufacturing compared to adult clothing. The basic data source for developing a methodology of 3-dimensional interactive child dress form is a mathematical description of child body surface. It is known that a child's posture has a direct influence on his/her body shape. That is why posture divergence from the one applied to clothing design induces major defects to fitting [3].

Generic body shapes are thought to account for 70% of all child population of our country. Though recent research done at MSUDT on Artistic design, styling and technology of wearing apparel department shows that children of pre-school age with standard posture account for a little more than 2/5 of all analyzed body shapes. These findings led to a conclusion that modification of child posture types classification by N. Volyanskyi is advisable for children's clothing design. Recommendations for individual body shape design were developed not only with consideration of spinal contour but also the frontal contour of a child's body (fig. 1, 2).
