This study presents an efficient clothes-sizing system for those experiencing obesity in old age with the aim of revitalizing the clothing industry for older obese people. The study targets 249 obese men aged 60 to 85 who satisfy a Rohrer index score of 1.6 or higher and a BMI (body mass index) of 25 or higher. Elderly obese males showed more obesity in the body based on the waist. In particular, those in their 60s were the most obese, and after reaching their 70s, characteristics of old age in which the stature was reduced and the limbs were tapered were shown. The clothes-sizing system was set to 5cm in stature, 5cm and 3cm in chest girth, 2cm in waist girth (omphalion), and 2cm in hip girth according to the KS standards. Through the two-way distribution of each section, the name of the section with a high distribution was given. Casual tops were selected from eight sizes, ranging from 155 to 170cm in stature and 95 to 105cm in chest girth. Suit top sizes were selected from eight sizes, ranging from 160 to 170cm in stature and 94 to 103cm in chest girth. Bottoms suggested 10 sizes distributed between 90 and 100cm in waist girth (omphalion) and 92 and 98cm in hip girth. According to the KS standards, the detailed size was divided into the basic part and the reference part.

The purpose of this study is to propose a specialized clothes-sizing system for elderly (aged 60~79) obese women satisfying the following conditions based on the data from the fifth Korean Agency for Technology and Standards (2004): a Rohrer's index of over 1.6, a BMI of over 25, and a WHR of over 0.85. The lower bodies of elderly obese women tends to be shorter and wider than average. Particularly, their torsos from the chest to the waist tend to be more obese than other areas. According to the KS standards, the clothes-sizing system sets up its size intervals as follows: 5cm in stature, 5cm and 3cm in bust, 3cm in waist, and 3cm in hip. Based on the dualistic distribution of each section, the names of the sections indicating high distribution are suggested. For suit tops, 11 sizes are selected as distributed in the 145-155cm stature section and 91-103cm bust section. For casual tops, nine sizes are selected as distributed in the 145-155cm stature section and 90-105cm bust section. For bottoms, 11 sizes are selected as distributed in the 82-97cm waist section and 91-97cm hip section. According to the KS standards, detailed sizes are suggested in the division of basic and reference areas.
