This study aims to prepare reference data that can be used to improve the size suitability of elderly men’s casual wear. The sizes of men aged 65–84 from the 8th Size Korea were analyzed and compared with those aged 45–54. First, as a result of classifying their body types according to Syzing systems for male adult’s garments (KS K 0050), more than 50% of the drop body types were “a protruding belly type (BB),” and more than 95% of the lower body types were “a thick waist type (B).” Additionally, elderly men with type BB or B were 3–5cm shorter in height, waist height, chest circumference, and hip circumference than middle-aged men. As there are currently only a few brands for elderly men, this means that the following problems may arise: If an elderly man wears a middle-aged man’s top based on his chest size, the chest and hip circumferences are adequate, but the length is insufficient, the waist circumference is insufficient, and the shoulder width is considered to be excessive. Similarly, pants designed to fit a waist size designation for middle-aged individuals will be larger than intended in terms of length, hip circumference, and thigh circumference.

Purpose: This study explored life experiences and meaning attributed to them by older men living alone during the pandemic of coronavirus disease 2019 (COVID-19). Methods: Data were collected from June to July 2022 through face-to-face in-depth interviews with 14 older men living alone and analyzed using the thematic analysis method suggested by Braun and Clarke. Results: The analysis revealed four themes and eight subthemes. 1) Unfamiliar daily life faced in old age due to COVID-19; 2) living a difficult life in a stopped society; 3) a life of constant effort amid change; and 4) daily life adjusting to the new normal amid regret. The participants volunteered to be secluded to adapt to their changed daily life in an isolated society, which led to depression. As time passed, they tried to adapt to their new daily lives by communicating untactfully to shorten their physical distance. Conclusion: This study suggests that it is necessary to understand socially vulnerable classes in national disaster situations and the need for various policies to respond to social isolation. In the future, developing an intervention that allows older men living alone to actively adapt to a changing society and verify its effectiveness is necessary.
