Women in their 50s undergo significant changes to their bodies, including weight gain and rapid increases in body mass index (BMI) due to menopause. This study aimed to develop a basic bodice pattern suitable for women with a “square” body type, which is the most common type among Korean women in their 50s. We used a body shape avatar representative of square-body-type women in their 50s, provided by 6th Size Korea (KATS, 2010) as the model. This avatar was loaded into a virtual fitting program to evaluate the fit of the research pattern. The results of the study were as follows. Using the 3D virtual fitting program, the ideal bodice pattern was found to be close-fitting, based on an analysis of the body surface of women in their 50s with a square body type. This population’s characteristic body features included a rounded back, forward-protruding waist, forward-tilted neck, and shoulder tips angled toward the center-front. Because of the protruding abdomen, the bodice’s waist dart value was lower than average. The base bodice design for this body type was adapted from the research pattern of Jun and Jang (2024). Adjustments for this study included adding 0.5 cm to the center-back length and designing the profile line from the back neckline to the armpit wall. Further, the front bodice waist dart was omitted to accommodate the protruding abdomen. After two rounds of revisions, evaluations of the virtual fitting significantly improved, with scores increasing from 2.38 out of 5 to 4.82 out of 5.
