This study aims to develop a fitted torso pattern suitable for males in their forties and fifties who are obese—a group that accounts for more than fifty percent of men in this age group—using a 3D virtual fitting program. Size Korea’s 2022 data for obese males in their forties and fifties is utilized for this study. In terms of the research method, a 3D program (CLO 3D) is used to implement the target group’s various body types and to apply fitted torsos that enable verification and evaluation of the pattern’s fit and ease. The characteristics of fitted torso patterns for obese bodies are as follows: the front centerline is a profile line; shoulder darts are added by reflecting waist-abdominal protrusion in the front panel; and shoulder, arm, waist, and center-back darts are constructed for the back panel. For obese bodies, the minimum circumference ease amounts should be approximately 6–7cm for the chest, 6cm for the waist, and 6–7cm for the hips. Based on an evaluation of the virtual fit of the developed fitted torso pattern, the data shows that a pattern (foundation) such as this is well suited for obese body types with an average of 4.67/5 points for reverse triangular obesity, an average of 6.67/7 points for log obesity, and an average of 6.69 points for the ease amount.
