This study aims to develop a detailed sizing system for lower body clothing for elderly obese women, using data from the 8th Korean Anthropometric Survey. The research targets 296 elderly women aged 60 to 85, selected from 805 participants in total, who meet the following criteria: Rohrer Index of 1.6 or above, Body Mass Index of 25 or higher, and Waist-Hip Ratio of 0.85 or greater. Elderly women with abdominal obesity exhibit shorter lower body proportions and greater fat accumulation in the torso, around the chest and waist. The findings show that women in their 60s have the highest level of obesity, while waist width and thickness are greatest in women in their 70s, suggesting that abdominal obesity increases with age. According to the KS standards, the main measurement categories were divided into 5cm increments for height, while waist and hip girth were categorized into 5cm and 3cm, respectively, to analyze the distribution of sections. Clothing size standards for lower garments that require a precise fit, such as skirts and formal pants, are presented in 13 sizes, corresponding to a waist girth range of 85–100cm and a hip girth range of 88–97cm. Detailed measurements are categorized into primary and reference areas. Additionally, sizes were presented differently based on whether a precise fit was necessary. For items that did not require a precise fit, ranges were indicated with letters, or ranges were indicated with measurements. Detailed sizes were categorized into primary and reference areas.
