Development of Upper Bodice Pattern for the Late Elementary Obese- Schoolgirls - Using iVirds 3.0 PB and iVirds 3.0 DS program -

Abstract : The aim of this study is to develop upper bodice pattern for obese girls aged 10~12 by using 3D virtual gar-ment simulation system. The criteria for subjects in this study were girls who had over 1.46 of the Rohrer Index. A totalof 229 schoolgirls who met these criteria were enrolled. The results of this study are as follows: First, by using 3D virtualgarment simulation, new upper bodice pattern considered obese-schoolgirls was development. The basic numerical for-mula were as follows ; bust girth B/2+4.5, armhole depth B/4-1, waist girth W/4+0.5+dart amount, front chest width B/6+2, back width B/6+2, neck width B/12-0.5 and neck depth B/12+0.5. Second, armhole darts were added to compensatethe loose amount of front armhole and dart manipulation was used to ensure a better appearance on armhole in the design.The dart side line was modified concavely to help cover the protruding stomach. Curved lines on the armhole were sig-nificantly relieved using dart manipulation and the darts side line was modified concavely to reduce the tightness aroundthe front waist darts. Third, according to the results of the new upper bodice pattern's appearance evaluation, it estimatedmore highly than existing pattern in silhouette and ease amount, confirming that new upper bodice pattern was appro-priate for the obese-schoolgirls. This study is expected to serve as one of important basic data for ensuing studies thatmay utilize 3D virtual garment simulation system with 2D patterns.
