The purpose of this paper is to propose a size-changing method with three-dimensional (3D) garment modeling for various body sizes considering vertical body proportions in addition to horizontal dimensions, while preserving the silhouette and ease of the original garment.


Cross-sectional dimensions and shapes of one dress form (the standard body) and jacket bodice were obtained by 3D scanning. The authors calculated horizontal multiplication factors of the relationship between the standard body and jacket bodice, and vertical body proportions. A target dress form was deformed using multiplication factors and vertical body proportions to construct a garment model that fitted the dress form. The method was verified using three different dress forms. The bodices of the jackets were compared with those obtained without adjusting vertical proportions.


Employing the proposed method, jacket bodices were made and fitted on target bodies while preserving the original shape. Jackets bodices made without considering vertical proportions had many wrinkles and deformed shape and poor fit around the bust line owing to the different vertical proportions. The vertical proportion is thus an important factor in the 3D garment modeling of garments of different size fitted on a body.

Research limitations/implications

The proposed method is a new size-changing or grading method for a bodice that preserves the original silhouette.


The proposed modeling method allows the construction of jacket bodice models and jackets of different size considering vertical body proportions. The method is applicable when making individually tailored garments or ready-to-wear garments for different targets.
