This study analyzes the participants’ purchasing and wearing conditions of Jiu-Jitsu uniforms, identifying issues with current designs and proposing improvements. Data were collected from 160 participants through an online survey from April 15 to May 20, 2024. Frequency, cross-tabulation analyses, and one-way ANOVA were performed using SPSS 29.0. The survey included questions related to participants’ general information, uniform purchasing behavior, satisfaction with Jiu-Jitsu uniforms, preferred brands, and sizing, and fit satisfaction. The results revealed that most male participants were in their 30s, while female participants were in their 20s. A higher proportion of males were overweight, while females were likelier to have a normal BMI. Participants generally owned 3–6 uniforms, most purchases in the 160,000–200,000 KRW price range. International brands were preferred, and participants selected uniforms based on fit, quality, and design. The most common sizes were A1 and A1L, with overweight and obese participants tending to opt for additional size options. Key improvement areas included pants length and waist width. The findings highlight the need for unisex pattern designs for individuals in the B range (160–170cm) and patterns specifically designed for overweight males in the C range (170–180cm). This study provides valuable insights into Jiu-Jitsu uniform preferences and body typespecific requirements, offering foundational data for enhancing uniform design and functionality.
